Answer 2

Explanation:

There are two main types of changes when something undergoes a change. One is the physical change and other is chemical change. In physical change, the physical properties of the object undergoes change however it can be reversed while in chemical change the state of the object cannot be reversed   . Now dissolving a substance into some solution can lead to a chemical change hence it is not reversible
