a If you are given some copper sulphate crystals how would you proceed to prepare its saturated solution at room temperature b How can you show that your solution is really saturated

Accepted Answer

a Take 100 g of distilled water in a beaker To this add one gram of copper sulphate crystals Stir this mixture with the help of a glass rod and dissolve copper sulphate crystals Similarly go on dissolving more of copper sulphate 1 gram at a time with constant and vigorous stirring A stage is reached when no more copper sulphate dissolves It is called a saturated solution at this temperature b Take this saturated solution of copper sulphate some solution in a test tube and add some copper sulphate crystals The crystals do not dissolve but settle down which indicates that the solution is saturated
