Hi professor, i dont understand why you would need to balance the reaction solution with the barium chloride example, you added a 2 to KCl to "balence the equation" what did you mean by that

Hi professor, great lecture! Always so thorough and informative in your explanations. I have one question: why does aqueous chemistry always take place in water? Can't the solvent be anything else? Thank you!

Hi Professor Hovasapian !

My question refers to the second example (part 26:10). If the ions do not react with each others, can we say that they are in an dynamic equilibrium ? (since there is no precipating species)

Thank you !

Hi Burhan.

I hope all is well with you.

The topics you mention run in a straight sequence one after the other for my course, so start with the Kinetics lesson and just move forward. The redox stuff is under Electrochemistry.

I hope that helps.

Best wishes.

Raffi

Hello Professor Raffi,

I live in B.C, Canada and the grade 12 Chemistry I am studying has the following,

1) Reaction Rates

2) Equilibrium

3) Solubility

4) Acids & Bases

5) Redox Reactions

Could you please tell me which lessons I should watch to help me study efficiently rather than watching lessons which I don't require for this course?

I would really appreciate that,

Thank You

Burhan

What's the formula of acetic acid? I consider it should be CH3COOH, and one molecule contains 4 Hydrogen atoms.

What's the formula H2C2H3O2?
