In an activity, a teacher dissolved a small amount of solid coppersulphate in a tumbler half filled with water. Which method would you use to get back solid copper sulphate from the solution?
(a) Decantation
(b) Evaporation
(c) Sedimentation
(d) Condensation
Evaporation can be used to get back solid copper sulphate from the solution. As the solution of copper sulphate is evaporated, water evaporates, leaving behind the solid copper sulphate.
Hence option (B) is correct .
