Problem
A monoprotic weak acid HX is dissolved in water to form a 0.150 M solution at 25 °C. The acid-dissociation constant for HX is Ka=1.8×10−5.
(a) Determine the equilibrium hydronium-ion concentration, [H3O+], in the solution.
(b) Calculate the pH of the solution.
(c) Calculate the percent ionization of HX in this solution and interpret what this value indicates about the strength of the acid under these conditions.
