Question

During science lab, Carl notices that when he adds water to his solid sample of anhydrous copper

copper sulfate, CuSO4, his reaction vessel

becomes warm and a blue solution forms. Describe what is happening

es )))

Answer 1

The dissociation of copper sulfate into ions is an exothermic chemical reaction that releases heat into the surroundings.

Step-by-step explanation:

Some of the potential energy stored in the solid sample of anhydrous copper sulfate is released as heat as the sample dissolves and dissociates into ions in the water. This is due to the large lattice energy of the crystalline copper sulfate.
