A mixture of sand and copper (II) sulfate pentahydrate can be separated by filtration due to the hydrate's water solubility, unlike sand. Filtration will yield copper sulfate in the filtrate and sand as the residue. Explanation: You can separate a mixture of sand and copper (II) sulfate pentahydrate by filtration because of a key difference in ...
