Final answer:
The addition of ammonium chloride to hypochlorous acid in aqueous solution does not result in a significant chemical reaction, meaning that no reaction occurs between these two substances under normal conditions.
Step-by-step explanation:
When ammonium chloride (NH4Cl) is added to an aqueous solution of hypochlorous acid (HOCl), there is not a traditional reaction like a neutralization or a precipitation reaction that you might expect between an acid and a salt. Ammonium chloride is a salt formed from the reaction of a strong acid (hydrochloric acid, HCl) and a weak base (ammonia, NH3), and it completely ionizes in water to form NH4+ (ammonium) and Cl- (chloride) ions. The chloride ions are inert and do not react further, whereas the ammonium ions can act as a weak acid. The hypochlorous acid, being a weak acid itself, does not engage in any specific reaction with the ammonium chloride solution under normal conditions. Overall, no significant chemical reaction occurs between ammonium chloride and hypochlorous acid in aqueous solution, so the correct answer to the student's question is B. No, a reaction will not occur.
