Solution: A monoprotic acid, HA, is dissolved in water: HA ⇌ H+ + A- The equilibrium concentrations of the reactants and products are [HA] = 0.240 M [H+] = 2.00 x 10-4 M [A-] = 2.00 x 10-4 M Calculate the value

Problem

A monoprotic acid, HA, is dissolved in water: 

HA ⇌ H+ + A- 

The equilibrium concentrations of the reactants and products are 

[HA] = 0.240 M 

[H+] = 2.00 x 10-4

[A-] = 2.00 x 10-4

Calculate the value of pKa for the acid HA.
