∙ 12y agono its a physical change, as it can be reversed, and it doesn't alter the element to become another element.
i.e. saltwater can be separated into salt and distilled water, and the elements don't change

What is chemical change when dissolving?
1. Dissolving with reaction - an example is dissolving in an acid - involve a chemical change because new compounds are formed. 2. Dissolving without a reaction - for example dissolution of table salt in water - is not a chemical change; only dissociation can occur.
Is a dissolving zinc in acid a chemical change or physical change?
Dissolving zinc in acid is a chemical change. It really isn't being dissolved, it is reacting with the acid to form new substances. For example, if you react zinc with hydrochloric acid, the products will be zinc chloride and hydrogen gas. The zinc seems to dissolve, but it is actually combining with the chlorine in the hydrochloric acid. Zn + 2HCl ---> ZnCl2 + H2
