Separating Mixtures

Aim:To separate a solution from a (precipitate is the name  for a solid that forms in a  liquid during a chemical reaction)

Equipment:

• Sodium carbonate solution.
• Copper sulfate solution.
• a Conical flask.
• Stirring rod.
• a 200 ml beaker.
• a Funnel or Filter paper.

Method:


               1. Pour approximately 50 ml of copper sulfate solution into a beaker.
               2.Add the same volume of sodium carbonate solution.A precipitation reaction will                                      occur,resulting in a cloudy blue precipitate of copper carbonate.
               3.Your teacher will show you how to fold the filter paper so it fits inside your funnel.
               4.Place the funnel,with the filter paper inside it,into the mouth of a conical flask.
                5.Stir,then carefully pour the precipitated mixture into the funnel.
