Answer: The solution will be an acidic solution when ammonium perchlorate is dissolved in water.
Explanation:
Salts are formed when an acid reacts with a base during a neutralization reaction.
Ammonium perchlorate is formed by the combination of perchloric acid [tex](HClO_4)[/tex] which is a strong acid and ammonium hydroxide [tex](NH_4OH)[/tex] which is a weak base.
So, the salt formed which is ammonium perchlorate is an acidic salt and its dissolution in water will make the solution acidic in nature.
[tex]NH_4ClO_4+H_2O\rightarrow HClO_4+NH_4OH[/tex]
Hence, the solution will be an acidic solution when ammonium perchlorate is dissolved in water.
