# What is the difference between copper sulfate, and copper sulfate pentahydrate?

May 2, 2017

$\text{Copper(II) sulfate}$ is a white salt..........

#### Explanation:

And $C u S {O}_{4} \cdot 5 {H}_{2} O$ forms beautiful, blue, macroscopic crystals.

So are the crystals blue? If so, you have the pentahydrate. And in fact I think you will find it hard to dry the pentahydrate.
