Answer 2

Explanation:

You will need clear water on top of the copper sulfate solution. There are two ways of achieving this. Either put the water in first and then, carefully so as not to disturb the water, pour the denser copper sulfate solution into a funnel in a long tube so the solution goes under the water. Or, put the copper sulfate in first and, using a piece of bent glass tubing as shown, carefully add the water, keeping its outlet just below the water surface as its level rises.

An optional variant is to put a strong sugar solution in the lower third of the jar, then add the concentrated copper sulfate solution, and finally the distilled water. Students will then see the copper sulfate diffusing against gravity as well as with it
