Question

When copper sulphate is dissolved in water in a beaker, a bright blue liquid or solution is formed. If copper sulphate is added until no more will dissolve, a saturated solution is formed. Some blue crystals will remain at the bottom of the beaker. What was the solvent used?

Answer 1

CuSO₄ is soluble in water. Its saturated watery solutions result in crystals of copper sulfate.

Therefore, the solvent used in this case was water.
