Question

Dissolution of ammonium chloride in water is aphysical change

Answer 1

nops it is a chemical reaction

Answer 2

Explanation:

When ammonium chloride is dissolved in water then it results in the formation of ammonium hydroxide and hydrochloric acid. The chemical reaction equation is as follows.

         $NH_{4}Cl + H_{2}O \rightarrow NH_{4}OH + HCl$

Thus, we can see that there is a change in chemical composition of ammonium chloride. Therefore, it is a chemical change.

Hence, we can conclude that dissolution of ammonium chloride in water is not a physical change.
