Expert Solution
Step 1

Given,

Concentration of aqueous Phosphoric acid solution = 0.48 M

 

 

Required,

                          Equilibrium molarity of HPO42- 

 

The pKa1 of phosphoric acid is 2.16 which is a standard value. This value will be used to find out the equilibrium molarity of HPO42-.
