Question

Quizplus · Accepted Answer

The expression for the concentration of HPO₄²⁻ in a phosphoric acid solution is given by the product of the first two dissociation constants (Kₐ1 and Kₐ2) and the hydronium ion concentration [H₃O⁺], divided by the sum of the terms representing the concentrations of all species in the solution.
