Acid/base questions

Hypochlorous acid dissociates in water to create hydronium ions and hypochlorite ions $HOCl + H_2O \Leftrightarrow H_3O^+ + OCl^-$H, O, C, l, plus, H, start subscript, 2, end subscript, O, \Leftrightarrow, H, start subscript, 3, end subscript, O, start superscript, plus, end superscript, plus, O, C, l, start superscript, minus, end superscript Suppose that additional hypochlorite ions are added to the solution. Which of the following correctly describes the resultant effect on the concentration of $HOCl$H, O, C, l?
