Ka or acid dissociation constant can be expressed using the reaction equation as:
A monoprotic acid, HA, is dissolved in water
HA ⇌ H+ + A-
The equilibrium concentrations of the reactants and products are
HA 0.150 M
[H+] = 3.00 × 10-4 M
[A-] = 3.00 × 10-4 M
Calculate the value of pka for the acid HA.
