Give a brief explaination of the two bonding factors which determine the strength of an acid.
Give a brief explanation of an Acid Buffer.
Define an acid and base in terms of the Bronsted-Lowry theory. Give two examples of conjugate acid/base pairs which adhere to this theory
Calculate the pH of a 0.02 M solution of benzoic acid which has a Ka of 6.3 x 10-5 at 25 oC where
C6H5COOH C6H5COO- + H
Thank you :)

This looks like a test. I will be happy to critique your thinking.
On iv, figure the conc of H+ first.
Ka= x^2/.02 where conc H+ is x.
then, pH= -log x
