- This video shows how you can calculate the Ka of an acid, if you're given the pH of the solution (and its concentration, of course). It's pretty straightforward if you understand where the Ka expression comes from (Equilibrium).

I have no idea why teachers make chemistry soooo complicated.. you just make it so clear. thank you so much. looking forward to my exams next week.i love your videos you are so funny.one love man.
i literally have a test in 1 hr and he just summarized what my teacher have been trying to explain for the past 3 weeks xD
How was ur exam 9yrs later?
@@Skyguy..how was ur test?
@@fawzibazzi6394 damn i cant remember cuz its been so longgg. And now im in uni yk. Um ik that i did rly well thats all i can remember!
This guy helped explain the poor explanation of most other websites.
When it comes to teaching as if teaching a 10 year old, this guy's the best. Not being sarcastic. It's a good thing.
As someone with an AP chem final in 12 hours, these videos are my life line. Not too long and still really good at explaining. Plus it isn't shitty camera quality. Thank you sooooooooo much!! ❤️
I love how he said "best of luck" at the end of the video, it feels like he's sending his wish of good luck for us on our exam later. Nothing, I just appreciated it!
Why aren't more teachers like you? That'd make education so much better!
"IIIIISN'T IT?" "OOOOH HOW DO U CALCULATE _____" someone turn him into a meme.
I love your enthusiasm it's hilarious and awesome
who starts of a vid with "ouuuuuuu"
will smith's cousin
He does, and does so fantastically.
😂😂😂😂😂😂
Said “oooouuuu” befor Young Ma 🤣
😂😂😂😂
This is exactly what I needed, thank you. Looks like I might actually be able to complete my chemistry lab questions.
How are you doing in life?
Thanks so much for this video! It made the complicated simple AND actually made me smile while learning chemistry.
I've been near the edge of pulling my hair out of how the hell you get the values for the equation.so if they give you a pH the value is substituted for the exponent that's with given [H+] value. then you plug it in.....alright that's It. I'm coming to you more now.
the video was great in identifying how to calculate the Ka ... however the stoichiometric is not complete. a compound cannot "by itself dissociate" ... therefore the real equation should be [ HClO + H2O H3O+ + ClO- ] ... even tho H2O will be ignored and not be calculated into the equation as its value would be 1 (because H2O can be a base as well as an acid)
this vid still helped me tho ... #respect
My world was just blown. And by that I mean I finished all my online chemistry homework (AKA Wiley Plus) courtesy of this video. Thanks!
EXCELLENT VIDEO!!!! Was stuck on similar hw problem and couldn't find method to solve online. This video answered it perfectly and concisely!
Great videos man, I love going on TH-cam and reinforcing what I have learned by reading and in class. Always looking for fresh new examples thank you.
I love the "~Isn't it?~". so clear n to the point much thanks
I wouldn't have been able to solve this without you. Thank you!!!!
this is extremely helpful
"use an ICE Table to figure ewwwt" 1:16

"ISN'T IT?" hahaha
This is awesome. Got my daughter from frustrated to understanding exactly what it means and how to do it.
Thank you! Good lord the amount of money I pay to go to college just to be confused and turn to TH-cam is ridiculous, but you definitely delivered!
What's your major?
Getting ready for a college chem quiz, thank you so much
Truly the best videos on the internet
Couple of years late but thanks for the help.. I'll never forget the ice table
Thanks man + love the attitude it's hilarious and entertaining that makes the video less boring 👍
ive been crying over this for last 15 minutes and it was this easy....i hate my chem prof
Thanks a lot for this! This is my chemistry teacher's achilles heel, and he struggles to explain it clearly sometimes. :P This was very helpful :)
I doth got an A+ thanks to your video, thanks m8.
"Do you even remember?" I love this
Love the positive energy my guy
Hi buddy, this was awesome. May I ask you the relevance of Ka? I am not from Chemistry background so I would want to know that by monitoring the Ka value of a weak acid, can we understand the effectiveness (sterilizing power) of the weak acid?
Well at least one of us is really stoked on Chemistry!
you teach better than my professor! thanks for this video. it helped a lot :)
owh... thank you so much now i can find Ka with pH value of monoprotic acid...love u
This guy is so enthusiastic he's making me smile. :)
and that's how you do it!! What an amazing video..
bless your soul. you make chem fun.
Wow man, glad you make this look easy. I really enjoy watching your videos!
How are u doing in life?
This guy is so hilarious!!! so much fun to learn.
This was really helpful, thank you. You got a new subscriber in me.
This spectacular ; i once performed similar problem and l was given 6 marks
ur voices sounds like the character in the tv series in big bang theory.juz kidding , Btw thx for sharing this videos with us! :)
wow thank you for showing your numbers on the calculator!!!!
Awesome explanation! I wish you were my professor!
thank you in these trying times, this helped so much
Final answer should have 2 sig figs, no? you only count the mantissa of the pH so it should be 3.4E-8
Wow! You have explained it well
When he said “ooouuu” I instantly became intrigued 😅
What if you have two concentrations? and the pH at half equivalence?
great videos! really helps with my chem final thanks!!!
My acid has 2 pKa's (sulfacetamide). How can I calculate how much of this acid (mass) I need to obtain a pH of 7.5?
Do i use the same techniques for a base? or is there something different?
Thank you SIR! I enjoy your videos, easy to learn.
video simple but very helpful! thank you
Hello and thank you for your great educational videos . I have one question pls : when we pour lets say 1ml of HCLO into lets say 3 L of water , then shouldn't the initial concentration of HCLO changed from 0.1 to 0.33×10^-4 ? , that is how concentration still stay the same with two different volumes ?.
Thank you in advance.
Thank you so much!
I feel I understand this better now
Can you solve without the calculator .it will be very helpful
Please🙏
why did you give the H+ the value of 4.23 and not ClO-? or it dose not matter?
never mind i got it
mathematically speaking, on the ice table, would it not be x/2 under H+ and ClO- ?
The way the guy's tone is so sarcastic HAAHAHHAH its cute dont get me wrong
Can't thank you enough.. This helped out a lot for my test!
How was ur test?
this only works with HClO??
Thank you so much ChemistNate!
Why is there 10 to the -5 in 5,89x10 to the -5
This guy is so funny. Nice explanation.
How you get 0.1 for HCLO|?
Thank you brotha, great explanation
Omg! Thank you do much for your explanation!
YES! I made progress :-)
Wow! Thank you so much for this video. The enthusiasm rocks :D
What is the meaning of Ka
God bless uu! ii have a test in ten minutes
Thanks a lot. I really appreciate this video.
I love this guy
This guy’s speaking way is sooooo interesting lol!
Wow well done sir.
Great video bro. Thanks.
super helpful, thank you!
This helped a lot!! Thanks!!!
Why is HCLO=0.1
my hero 🙏
is -logH+ the same thing?
Yes
you are awesome !!! thank you so much
Why is H+ and ClO- zero when we do the ice chart? Can anyone explain that to me? thanks :)
This is because there is no amount of either of them present in the solution INITIALLY.
Imagine you have an empty beaker. It is then filled halfway with water. The very INSTANT you pour in an acid (let's say HCl), the only thing present in the solution is HCl and H2O. This is because INITIALLY the HCl has not had a chance to ionize (dissociation). The reaction must proceed forward in order for there to be H+ and Cl- ions in the water in order for there to be values in the ICE table, which is why there is a +X CHANGE in the ICE Table and a value available after the solution (and reaction) has reached equilibrium.
I hope this helped! Good luck!

I understand it now!!!
you’re the goat
something about this guys voice is making me lol
All hail the chem god
Damn you’re fun to learn from!
Why is this so easy now?!?!
You helped me so much!!!
you make chemistry sound so fun but actually it isn't let's be honest 😂😂😂
thank you thank you thank you!!!!!!!
thank you so much!
great vid you rock
someone needs to make a meme of the oouuuh
THANK YOU
Cheers buddy!
