At 1:48, I think the third chemical equation should read as follows in order to be correctly balanced: H2SO4 + Ba(OH)2 --> 2H2O + BaSO4 Correct me if I'm wrong.
Ya extremely clear explaination but the problem is here suppose your teacher asks you whether chromium trichloride is an acid or not an acid/base the what would you answer this is the point where i got stuck at my exam and lost a mark whereas i am a topper and know that it is both an acid and not an acid at the same time (no offence)
Not at all. All the theories discussed are correct. What's different is that each one, in the order discussed, covers a broader range of reactions then the previous theory. So, Theory 2 agrees with what Theory 1 says is an acid-base reaction, but _also_ classifies even more reactions as being acid-base reactions. Then Theory 3 agrees with Theory 2, but also describes more reactions, and so on.
This is the most effective presentation for Chemistry I've seen. THANK YOU! Hope you post more videos!
I haven't added to the comments in a long time-thank you!, to everyone that left such kind comments. I'm very happy that this video helped anyone. :-)
Very clear and helpful description, thank you very much!
Great presentation! Very easy to follow and so helpful.

You're right! I misplaced the subscript 2 inside the parenthesis. I hope that didn't trip up anyone.
Clear and concise...awesome

@@suchismitadas3713Ma'm. It's been six years since I studied this subject. I don't remember much from it. Best of luck with your studies, though!
Very good, thanks!
thank you for explaining ! :)
No Problem. Thanks, you helped me with my chemistry test!
Awesome
my student can review the theory of acid and base with your present,thank you.
Lowry theory is wrong or what???
