Plenary ( Mark students work)
At first, you can see the copper sulfate, but then the crystals disappear but the blue colour remains in the water. The copper sulfate is the solute. The water is the solvent. Other common solutions are dissolving sugar in tea or coffee, dissolving instant coffee granules in hot water, and dissolving powdered cool drinks in water.
