Professor Hovasapian, I want to thank you very much for teaching all this material in such a wonderful way. Thank you for your time and dedication to the students. Also, I was wondering if there is any way you can upload lectures on Organic chemistry, as organic chemistry is a very complex subject and having someone like you teach it, would certainly make things less complicated. Thank you once again!

Buffer

When you add acid or base to a buffer, do the stoichiometry of the neutralization first ( in moles ), then do the Equilibrium problem ( in molarities ).
Using the Henderson Haselbalch Equation with buffer solutions can save time and effort.
