Take half litre water in a beaker.Add small amount of Potassium Permanganate to it.Observe the colour and see the concentration of the solution.Open up the tap.See that the quantity of the solution increases.Now again note the concentration of the solution and find thedifference.When the solution is evaporated observe the change in  colour and concentration 
 +
Repeat the process with different salts.
