Give a brief explanation of an Acid Buffer.
(iii)
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
(iv)
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 :)

  • chemistry -

    This looks like a test. I will be happy to critique your thinking.

    On iv, figure the conc of H+ first.

    Ka=[H][C5H5COO-]/.02

    Ka= x^2/.02 where conc H+ is x.

    then, pH= -log x
