Use the Henderson-Hasselbalch equation to solve part 1.
For part 2, the conjugate base (we'll call the molarity M) is
............A^- + HOH ==> HA + OH^-
initial.....M..............0.....0
change......-x.............x.....x
equil......M-x.............x.....x
Kb for the A^- base = (Kw/Ka for the HA).
What is the pH of a buffer solution made from 0.20M HC2H3O2 abd 0.5M C2H302^-.The ionization constant of the acid (Ka)(HC2H3O2)is 1.8multiplied by 10^-5.
(ii)Calculate the ionization constant of its conjugate base
