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?
CuSO4 is soluble in water. Its saturated watery solutions result in crystals of copper sulfate.
Therefore, the solvent used in this case was water.
