Quizplus · Accepted Answer

The correct net ionic equation for the reaction when HCl is added to a HOCl/NaOCl buffer solution is $H^+ + OCl^- \rightarrow HOCl$. This equation shows the reaction of the hydrogen ion (from HCl) with the hypochlorite ion (from NaOCl) to form hypochlorous acid (HOCl), which is consistent with how a buffer works to neutralize added acid.
