For the generic equilibrium HA(aq) ⇌ H+(aq) + A−(aq), which of these statements is true? For the generic equilibrium , which of these statements is true? The equilibrium constant for this reaction changes as the pH changes. If you add the soluble salt KA to a solution of HA that is at equilibrium, the concentration of A− would decrease. If you add the soluble salt KA to a solution of HA that is at equilibrium, the pH would increase. If you add the soluble salt KA to a solution of HA that is at equilibrium, the concentration of HA would decrease.

Answer:

The correct answer is The equilibrium constant for this reaction changes as the pH changes.

Explanation:

The equilibrium constant of a reaction depends of pH and viceverca.There is a equation that link pH with equilibrium constant Ka(for assumption).The equation is given below,

    pH=pKa+log[A-/HA]  

where[A-] is the concentration of conjugate base and [HA] is the concentration of conjugate acid.
