why am i only learning about this the night before my final. oh my god. this is so amazing. she's better than my chem teacher at explaining things. thank you so much.
Thanks for putting the formulas up! You're really good at filtering the extra info that might give context for more advanced students but easily confuses beginner students. I come to your channel to get a fundamental breakdown of my 2 hour lectures lol. So thank you!!
oh my gosh. THANK YOU. I've been staring at my textbook for hours over this and haven't been able to sort out which formula gives you what- the summary at the end was a LIFESAVER!
I don't know why you don't have 50 mil subscribers because you are actually the best tutor out there. All the other tutors are so complex and you just get right to the point.
You are a wonderful human being, thank you so much for making them! :D You're editing skills are amazing plus you explain everything so well! I love how colourful and fun your videos are, you make chem fun. I hope you get tons of subscribers in the future, like this channel is great! :DDD
i love you thank you so much, i hate online school so much because we have to read everything from the textbook and i can't understand it. you made it really simple and easy to understand thank you so so so much
This woman is amazing!!!!!! Been stuck on a question like this for over an hours and pithing 2 mins of watching this I actually get it!!!! Thank you so much :)
Thank you so much for thiss, I was literally crying cause I can't understand anything, but with the help of your video, I immediately understand it and can answer it in a piece of cake, thaank youuu
We are not subscribers... we're students 💁🏾♀️ 😅 Thank you Melissa 😊 you are officially added to my college A team! I'm On my way to finally get my bachelor's degree 🙌🏾 😌
you. are. a. life. saver. Thank you so much! I barely understood the lesson in my chemistry class, but you explained it in a much detailed and better way. This will be on my final so this definitely helped!
they are making us do this for 7th grade online school and don’t explain it well enough and i’m coming to this video after a mental breakdown from it 😎
i have zero interest in chemistry which is probably why it’s so hard for me to learn, but 4 minutes from your vid made more sense then all the notes I had to look through😂thanks
I got the same result. If you have the pH already, to find pOH just substract the pH=8.5 to 14 (pOH = 14 - 8.5 = 5.5). Once you found pOH= 5.5, you can find OH. To find OH use this formula [OH-]= 10 ^- pOH. [OH] = 10^-5.5 = 3 x 10^- 9 or 3.1 x10^-9. The sig fig will depend on your professor really.
Finals are coming up and your videos, along with the step by step notes I purchased, have definitely helped me feel more confident about these exams! Going to put all of this to use tomorrow, Thanks Melissa! Hopefully I pass because I need to graduate in 2 1/2 weeks lol
Thanks, I haven't made a video on this yet, and I needed to share one with my students. Going through all the youtube pH videos, this was the only one that was both correct and understandable.
I have not done calculations like this in a number of years and it would be really helpful if someone would step through exactly what you select on your graphing calculator and also going the reverse; if I have the [OH-], then what do I plug in to get to [H+].
This is not fair! Some people wrote in the comments that they watched this video before they entered the university finals. And the problem is that I have to learn this as a high school student in Turkey. Moreover, this is known as one of the easiest subjects! It wears me out that I can't even go to university without knowing these chemical calculations.
Hello! This was a really helpful video. I'm currently in chemistry Higher Level in the IB system and we are learning about weak acid and base dissociation constants (ka, kb, pKa, pKb) and their calculations and I was wondering if you had a video about that or if you can make one as I'm finding them rather difficult.
Perfect timing on my next Live session this Sunday at 12PM PST, I will be going over how to find the Ka and Kb. th-cam.com/video/8ZLifdOOzqA/w-d-xo.html
May I ask some question, Suppose if we have hydrolysis ammonia NH4+ NH3 + H+ Kh = [NH3][H+]/[NH4] = 10^-9 mol/L To 1 liter of pure water, 1mmol of ammonium chloride was dissolved, and pH was adjusted to 9 using sodium hydroxide. What will be the concentrations of ammonium ion and free ammonia?
minute 2:36, How do you do the division of 1x10-14/3.1x10-9? I thought yo had to subtract the coefficients? I must be doing something wrong I get -5 not -6. Please help Melissa. PS thank you so much for all this work. Wait a second I got it, it is the rounding, I was using 3.1 not 3. Got it

ugh same sis my final is tomorrow too
HAHA me too! hope you guys did well!
Yes we sure do mine's tomorrow but your's 2 years ago
mine is tomorrow lol
I am the one who is watching it before 3 hours of exam .
You are literally the reason I passed my chem class in the summer ! I recommend you to everyone I know taking chemistry this semester
Yay!! Congrats on passing especially in the summer! Thank you so much for recommending me I really appreciate your support 💕
Same

i dont know what i would do without you melissa, when i get my degree i wish i can thank you in person. your literally my tutor
who else is here during Corona?
me....chem makes no sense and i'm so done
@@ifoundmyberries4203 same, it does not register in my brain whatsoever
Yeah, this virus sucks.
The pOH, pH, H+ and OH- concentration conversions are at 3:04 You're so clutch for this!
Why can’t I understand chemistry! I’m trying so hard and I just can’t my brain doesn’t work
Alondra Lozano same problem
I feel u
Here too same problem
Same here
Cause you're overthinking it
You literally make the coolest videos ever. You taught me more in 5 minutes than my teacher could in 2 hours. Thanks!
oh my gosh. THANK YOU. I've been staring at my textbook for hours over this and haven't been able to sort out which formula gives you what- the summary at the end was a LIFESAVER!

This woman is amazing!!!!!! Been stuck on a question like this for over an hours and pithing 2 mins of watching this I actually get it!!!! Thank you so much :)
I've been struggling learning this for weeks and now I learned them in 4 minutes. You are awesome ❣️
You can tell that you put a lot of heart into this, thank you.
was struggling with the concepts, but after watching this video it makes sense. Thank you Melissa Maribel
I passed my chemistry all because of you, youre a life saver
Im literally crying thank you for this.
You're welcome!
Thank you so much for thiss, I was literally crying cause I can't understand anything, but with the help of your video, I immediately understand it and can answer it in a piece of cake, thaank youuu
This was so helpful! 💗 I love how you explain it step by step in a simple way. My chemistry teacher can be a all over the place sometimes. 😅
You're a life saver have an exam today. You made it more easier to understand, thank you very much!!!!
My daughters score went from a 54 to a 90 thank you for what you do. I haven't seen a smile that big when it came to chemistry! Thank you.
WOW!! That is an amazing improvement! I'm so happy I could help 💕
You're an angel for helping us chemistry students. Thank you
Thank you so much for this video. It really helped!!! I can now just use the formulas and figure out the answers instead of struggling. Thank you!
youre a better teacher than my actual chem teacher god bless
We are not subscribers... we're students 💁🏾♀️ 😅
Thank you Melissa 😊 you are officially added to my college A team! I'm On my way to finally get my bachelor's degree 🙌🏾 😌
Incredible tutoring sesh. Thank you SO MUCH
Holy crap I just found the pH Grail!!! You answered all my questions THANK YOU THANK YOU THANK YOU!
In 2nd Q: problem b -- where did you get [OH-] = 3 x 10^-6? I got 10^-5 M?
I did too
Literally you’re the reason I’m passing AP chem
🤷🏽♂️ im lost!!1 great video :)
Gracias Leo! 😊I'm sure you're thankful you aren't taking Chemistry 😂
aim very thankful , 😂
Thanks for the clear instruction. Easy to follow.
I’m taking bio 103 and Chem 104 this helps a lot 🙏🏽🙏🏽🙏🏽 especially with exams around the corner.
Even before watching any of your videos I make sure to hit the like button because I usually forget to do it when I click on your next video
Literally you're amazing tutor more than our school teachers 😊🎉
can we take a moment to appreciate the effort
thank you so much you helped me alot.
Aww thank you for noticing!
This video helped me understand the formula so much!
thank you melissa. i just understood how to do this and i have a test soon. thanks so much. i liked and subscribed
you lietrally saved my 30 mins thanks
THANK YOU SO MUCH ! I DIDNT UNDERSTAND WHEN THE TEACHER EXPLAINED IT BUT NOW I DO
how have i not found your videos before! you're awesome
you. are. a. life. saver. Thank you so much! I barely understood the lesson in my chemistry class, but you explained it in a much detailed and better way. This will be on my final so this definitely helped!
Her videos are so pretty 🥺🤧
test in three hours your a life saver
THE BOMBBBBB :D Thank you Melissa!!
they are making us do this for 7th grade online school and don’t explain it well enough and i’m coming to this video after a mental breakdown from it 😎
Hope this video helped!
At this point you are my guru in chemistry 😭thanks so much
i have zero interest in chemistry which is probably why it’s so hard for me to learn, but 4 minutes from your vid made more sense then all the notes I had to look through😂thanks
Your amazing! I'm going to use this on my test! Thank you!
How did she get 3x10^-6? For oh-? When I did it, I got 3x10^-24
Same, honestly I kinda wished she had showed the calculator 😢
I show the calculator part in my new series here: th-cam.com/video/XnxBPM3XTWo/w-d-xo.html

@@melissamaribel I got an 88% !! Thank you so much!!
Congratulations 🎉🎉🎉
Absolutely the best!! Wish you were my instructor!!
You just saved my life
thank you so much you really helps me out with summer school
Thank you so much. You are so much easy to understand than my teacher. I passed the final, thanks to you!
Just found your video after struggling with these equations for like 2 hours-- you've saved my grades haha.
Thanks, I haven't made a video on this yet, and I needed to share one with my students. Going through all the youtube pH videos, this was the only one that was both correct and understandable.
Hey it's Ketzbook!!! 🎉
@@melissamaribel yup, thanks for your vid ;)
Best explanation ever!!!
Oh now I get it. Thank you so much!
I have not done calculations like this in a number of years and it would be really helpful if someone would step through exactly what you select on your graphing calculator and also going the reverse; if I have the [OH-], then what do I plug in to get to [H+].
I love this woman
Really? It's THAT simple? WHY must they make it so hard. Melissa you're a saint!
Aw thanks Chloe, so happy it's a lot easier now :)
Thanks!! Very helpful and clear to understand.
Im at a 26% in my chem class and I wish I had found you earlier 😭
How u doin
Eli is that you
Can u explain further how’d you find the pH 3.39?
You are my savior
TYSM UR A LIFESAVER!
You really make things seem so simple.😀😄😀😄
You make things easier.... Can you make a video on molecular orbital diagram please 😢🙏🙏. You make me understand
i understand.. you are the best teacher😍😍😍😍😍😍 i am from bangadesh
Thank you for this awesome video! I always have trouble figuring out what formula to use! you broke it down barney style, my kinda style! Cheers!

my chem teacher was absent and told us to watch this 💀
Your jus beyond amazing thank you so much college chem has been so hard cause we learn one thing in class and it’s different on the hw
YOU ARE AMAZING AT EXPLAINING THANK YOU!!!
THIS IS SO HELPFUL! THANKS FOR SAVING MY LIFEEEEE!!! 💕💕💕💕😭😭😭😭
So happy to hear 😊
This is so helpful!!! Thank you so much!
Thank you, Melissa. You are amazing
Oh my god thank you so much for this video Melissa!!!
Omg such a life saver 😭😍
Thank You So much This helped!
Thank you for helping with chemistry!
You're welcome!
Instead of me watching over an hour and a half of zoom video lectures for my test tonight I just watched this😂

I'm sure the information is good but you are going entirely too fast for introductory chemistry students.
It’s hard to keep on track. Great information though. Thank you
i literally love u thank u sm bae
Literally just helped me do an entire assignment!😂 subscribed IMMEDIATELY❤️
Yay!! Thanks Annabelle for the support 😊
May I ask some question,

THANK YOU!!!
This just helped me so much, thank you. :)
thanks mam... from bangladesh
Whats the formula for ( H subscrip 2 O positive) ?
Is H30 replaced by H+ in this video?
H+ and H3O+ both refer to an acid so either one is correct
@@melissamaribel oooo
where did you get 14 from the POH equation ???
minute 2:36, How do you do the division of 1x10-14/3.1x10-9? I thought yo had to subtract the coefficients? I must be doing something wrong I get -5 not -6. Please help Melissa.
PS thank you so much for all this work.
Wait a second I got it, it is the rounding, I was using 3.1 not 3. Got it
How do you calculate for these (pH, pOH, H3O+, and OH-) if a value in M is given?
This was so helpful
Soooooo simple thank you
