How is this terminating the reaction (more info inside)?

Question

In my chem lab, we had a solution of 1 drop bleach (5.25% NaOCl) and 1 drop 0.1M HCl. After it reacted for a bit, we added 1 drop of NH3. The question is "explain how this terminates the reaction using words and chemical equations." I think I get the word part (wouldn't the NH3 just neutralize the HCl, and then the NH3 doesn't react with the NaOCl?) but what about the equations?

Answer 1

NH3 reacts with both HCl and NaOCl. With HCl it forms NH4Cl, with NaOCl it forms cloramine (NH2Cl - gas) and lye (NaOH).
