Problem
A 0.10 M solution of the weak monoprotic acid HA is at equilibrium according to HA(aq)⇌H+(aq)+A−(aq). Pure water is added until the volume of the solution doubles. Will the pH of the solution increase, decrease, or remain the same after the system reaches its new equilibrium? Provide a brief explanation.
