Problem: (a) What is the pH of 0.65 M potassium formate, HCOOK?

FREE Expert Solution

We are asked to calculate the pH of 0.65 M potassium formate, HCOOK solution.

This salt contains K + and HCOO

  • HCOO is the conjugate base of the weak acid, HCOOH. 
  • Therefore,  HCOO is a base in water. 
  • Ka (HCOOH) = 1.8 × 10−4


The dissociation of HCOO is as follows:

HCOO(aq) + H2O(l)   HCOOH(aq) + OH-aq);
