So.. I'm in 11th grade! and we have this topic for our finals. My chem teacher sorta makes everything more confusing.. for my test, I ended up spending like 2 weeks just to end up memorizing this! So grateful I found this video before my finals!! I can finally solve the reactions on my own. Thank you, professor Dave!
It just feels so good when you learn something. At first I could follow everything that was explained, but couldn't do the exercises myself, and now after studying for a week for my first university exams doing the exercises just comes to me naturally. This video has been a huge help, so thanks for that.
You are a hero. You are making it possible for people to learn chemistry by your clear, concise and useful instructions and demonstrations. I believe you are opening the doors of opportunity for many people, who may not otherwise have the opportunity to excel in the sciences. I believe you are improving the lives of your viewers and hopefully the condition of the world. You are improving my life by helping me pass chemistry so that I may enter graduate school and work towards a masters degree. Thank you Professor Dave.
You will not believe this but I have been practicing Redox rxn for 2 years and if a gap occurs of two-three months I forget half-redox method. But with this easy explanation I will never forget it and for that you have my highest gratitude.
As a college student, part of me really wishes I took chemistry while I was in highschool… and precalc/trig… college doesn’t always take into consideration…
i have an ap chem quiz tomorrow and this makes it easy so i have more time to study for my calc test thst also happens to be tomorrow, youre a lifesaver!
THANK U, i didnt get anything my teacher said and was kinda worried cause this qn carries like alot of marks in my exam which is in 3 hours. you just saved my life and that 3 marks. Thank you soo much
This was good but the step where you add electrons could use a bit more clarification. I get it, but only after rewriting the half reactions as one long equation. Maybe annotate that part of the video to eliminate ambiguity as to what left and right actually mean. Again, I got it, but not at first until I stared at it for a little.
Thank very much I have been trying to balance redox reactions for days you didn’t show us how to combine to to reaction after multiplying the electrons pls do a video I would be grateful
hey can u pls tell how to identify wether the rxn took place in acidic or basic medium?? if u hv alreasy uploaded any video regarding that can u pls give me the link for it...
I don't mean to be rude, this guy is epic and smart, but people looking at this and calling it easy are a bit crazy. I'm writing this out by hand step by step to try get it into my mind, and every time I think he is going to say "Done!" he says "And now..."
Can someone explain how the dichromate ion was reduced to Cr^3+ and how the Fe^2+ was oxidized to Fe^3+ cause I did understand that k ions and the sulfate ions are spectator ions and they are neglected to see what happened in the reaction.
How does Prof Dave clearly explain a 30-min lecture in eight minutes? Amazing!
Nah, it’s a 45 minute lecture in 8 minutes

I've been trying to understand this in a simple way for an entire day, this is the most clear explaination i've found, thanks a lot!
ive been coming to this same video for years now, every time I forget how to do these. This is the absolute BEST explanation on yt on how to do this.
Absolutely. Short n Crisp.
THANK YOU SCIENCE JESUS

I'm from Philippines, it really help a lot Professor Dave, please make new ones to help a lot of people, Thank you so much
Thank you very cool Kanye
Ang hirap kasiiu
Dude you are saving me in college. Thank you so much.
Same. Optometry student here
@aface cadcae ...you don't know how colleges work, do you ? Lmao
Am from cameroon ,and I don't mind washing this video in 2021 .it really help me to write my chemistry exams thank you so so much prof dave
You shall not wash videos! Thank you.
I was looking for the difference between acidic and basic solution and couldn't find why it even exists. Very nice instructions. Thank you
thanks dave! revised the whole thing in 7 mins , an absolute bomb video
I spaced out when my teacher was teaching this for just a moment and it got so complex, but you make it sound so simple! Thank you
Thank u sir my school teacher takes test of these reactions tommkrow it help me lot and for final exam it's so imp....
Thanku sir
All of these ppl are studying this concept in universities in other countries while I'm studying the exact same thing in 11th grade in India😢😢😢😢😢
us bro us
AS level here❤
Why must we study this while other get to chill brother?😢
Same here😢
I envy u for being forced to study this at an early age
Prof, you made this concept soo clear in just 7 min . You are amazing!!
this is much much way better than any other video
Thank u so much sir...I used to face difficulty in this concept, and ur video clarified my doubts to the fullest. Thanks a lot!!!
I rewatched this video over and over for my homework, it’s helped me so much in class, thank you so much 😭😭
Thanks sir for making m'y understanding easy😊
I'm from India studing in grade 11. Your videos help me a lot in understanding things more clearer.
As a college student, part of me really wishes I took chemistry while I was in highschool… and precalc/trig… college doesn’t always take into consideration…
What a relief when you solve an equation and the answer is right !!
Professor Dave is awesome. This dude and The Organic Chemistry Tutor are lifesavers. Absolute lifesavers.
literally teaching me the whole course, thank u!
i have an ap chem quiz tomorrow and this makes it easy so i have more time to study for my calc test thst also happens to be tomorrow, youre a lifesaver!
professor Dave and organic chemistry tutor (GOAT)
Your explanation is perfect prof
Greetings from Egypt ♥️♥️♥️
Succinct, comprehensive, and digestible, thanks man
always struggled with balancing complex redox rxn, this video rlly helped me out. THANKS!
Thank you so much 💖 for teaching them to me the first time
Came back here to review too 😂❤
Dude this is literally the perfect video for explaining this
THANK U, i didnt get anything my teacher said and was kinda worried cause this qn carries like alot of marks in my exam which is in 3 hours. you just saved my life and that 3 marks. Thank you soo much
Well explained! Thnx! U summarised a 2hour lesson in 7min
This guy just saved me from impossible chem quiz tomorrow. Respect 👏🙏🙏
Have an exam tomorrow

Professor Dave needs to be shown as a resourse in every college class he is amazing
YOU ARE STUDYING THIS IN COLLEGE WE ARE STUDYING THESE ALL IN 11 GRADE
@harshavardhan.69 it's taught in chemistry. Chemistry is taken both in high-school and college.
@@alexawermuth1219 yeah but balancing is not in high school am I right?
@@harshavardhan.69 I can't remember
Professor Dave and Tyler DeWitt are my saviors
After this video now I created a rule to balance these redox reactions half equation -> balance moles ratio -> H2O -> H+ -> e-(balance charges)
You just did what my teacher couldn't do for a week straight. Thank you so much
This was good but the step where you add electrons could use a bit more clarification. I get it, but only after rewriting the half reactions as one long equation. Maybe annotate that part of the video to eliminate ambiguity as to what left and right actually mean. Again, I got it, but not at first until I stared at it for a little.
My chem teacher doesn’t teach us the material at all so this really helps
BEST VIDEO, IM FROM INDIA BUT THIS IS PERFECT FOR ANYONE TO UNDERSTAND REDOX IN JUST & MINTUES> HATS OFF
I think my teacher on chemistry also watched this video, because the thumbnail was the no. 1 question in our process part of the test😂😂😂😂
I was banging my head against this concept for a while, understood more about the concept from the 7mins video then a week of practice problems
This guy is a really good teacher he broke it down for me better than they taught me in school
I'm from Fiji and your explanation is too good professor 💯👏♥️
Thank you very very much to a real proffesser
I had been searching for a good video to understand this for hours and finally came across this and understood it straight away thank you so much
it feel like a whole new world after this, thankssss!!! :))
Thank you this really help me a lot
I like your explanation than my teacher's explanation
You deserve more subscribers
thank you so much man i have my chem taste in 6hrs cureently studying with ur vid at 5am
Amazing explanation ❤️💫
God bless you Prof Dave. Short and very straight ❤
Crystal clear explanation, thank you, sir
I a student from India wish u a Happy teacher's day sir
You are life saver in science
professor dave really is the G.O.A.T
This one really helped me
My Text book failed to explain it clearly. 👍
I am from India before my medical exam I am here to read fast thanx
Good luck😇
I have my exam tomorrow and this was super helpful for clearing up all my confusions. Thanks a lot🙏
Thank you. I can finish/Start my homework!
Oh my god thank u . Its really the easiest way to balance in case of basic medium . I love it .
Wow they way he taught it is amazing. Now i totally understand the concept. Props to you Prof . Dave!!
Instead of counting electrons after balancing O and H then balancing , do it before that , its a lot faster and easier
Keep it up bro thanks for every thing you helped me by the worst and the hardest portion of chemistry . may God bless you
I always loved your intro animation 😂
thank you Professor Dave Explains!!
At 6:47, how did you find 3 multiply by HNO3+H2O->NO3^- +3H^+ + 2e^-? Wouldn't be 6 multiply by these equation?
The reason he multiply it by 3 is to make the e- in the two equation balance
I'm stuck with the same question... I also thought it was 6, I don't know why it's 3. Did you ever find out?
dave grohl is teaching me chemistry no way
C2O4-2 + Mno4 _ co2 +Mn+2
Can you balance this equation using this rules in the video ?
Yes, you can. Just did this.
Omg this is really amazing, you helped me a lot thank you so much
that really saved my life
My difficult topic is now easy peasy. Thank u sire for this❤👍
Ur the best teacher alive:-)
This video literally saved my exam
Thank very much I have been trying to balance redox reactions for days you didn’t show us how to combine to to reaction after multiplying the electrons pls do a video I would be grateful
Tried to learn it from various places ....finally understood from you . Thank you professor ! 🥹
Tqvm sir🙏🙏🙏🙏 your teaching method is very intresting 🙏🙏🙏🙏🙏this is very help full for me😊🙏🙏🙏
You forgot to add a 2 in front of the Cr in the question.
Like always fanastic 🎉🎉🎉🎉🎉
5:45 : *cancel waters if possible*
me attempts practically to cancel waters
BIG BRAIN TIME
Thank You Sir, this video really helped to understand!!
Thanks for using the reactions to teach us that i want.. D and f block chemistry 12th standard in preparation of K2Cr2O7
thanks chemistry Jesus, you're truly life saver
Thanks god.
There will be an exam in next two hours...........
This just helped me
Thanks a lot I am stuck in this problem ❤
hey can u pls tell how to identify wether the rxn took place in acidic or basic medium?? if u hv alreasy uploaded any video regarding that can u pls give me the link for it...

Professor dave,is the general chemistry playlist done or is there more to be added and thank you for the effort you put into these videos❤
Thanks profesor i Can now balance a redox reaction ❤️
Hello sir.
How can you identity if a reaction is Acidic or Basic before balancing the equation?
Simply if H+ is present during balancing the reaction then it is acidic medium and if OH - is present then it's basic medium
Can someone explain how the dichromate ion was reduced to Cr^3+ and how the Fe^2+ was oxidized to Fe^3+ cause I did understand that k ions and the sulfate ions are spectator ions and they are neglected to see what happened in the reaction.
दवे sir की जय 🙏🏻
How did you get +6 in the first example for the dichromate?
oxygen is -2, times 7 is -14, the ion has a formal charge of -2, so that's a total of +12 shared between two chromium atoms, so +6 each.
Very good explanation sir
You've just helped me solve one of my biggest concerns regarding redox reactions and electrochemistry and I cannot thank you enough
