Separating a mixture using evaporation

AIM - To separate a solute from a solvent in a solution evaporation.



METHOD -  1  set up the Bunsen burner, tripod and gauze mat. Don't place the Bunsen burner under                               the tripod yet

                      2  Add approximately 50 mL of hot water to your beaker and place it on top of the tripod                             on the gauze mat

                      3  Add enough copper sulfate solution to quarter fill the evaporating basin

                      4  Carefully place the evaporation basin on top of the beaker

                      5  Light you Bunsen burner. open the air hole and gently push the Bunsen burner under                             the tripod

                      6  Heat the solution until most of the solvent has been evaporated and crystals of solute                                 are  forming
                     
                      7  turn of your Bunsen burner

                                                                              RESULTS -

DISCUSSION - We put the solution ( Copper sulfate ) in the evaporating basin and used the Bunsen burner to heat the solvent ( Water ) so it can speed up the evaporation process. After the period we left the solution on the window sill for it to naturally evaporate and left it there for 2 days. We checked on it again and it turned in to a solute( Solid copper sulfate Crystals ) ------ >
