Question

When copper sulphate is stirred into water, the water turns blue. What two tests
could you carry out to see whether this mixture is a suspension or a solution?​

Answer 1

When water is then added to the anhydrous compound, it turns back into the pentahydrate form, regaining its blue color, and is known as blue vitriol.Copper(II) sulfate pentahydrate can easily be produced by crystallization from solution as copper(II) sulfate, which is hygroscopic.
