Filtration Experiment

We are doing an experiment to separate two chemicals from a mixture that we make.

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

Hypothesis: I think that the small particles will pass through the filter and the larger particles won't.

Method: 

1. Pour approximately 50 ml of copper sulphate solution into a beaker.

2. Add the same volume of sodium carbonate solution. A reaction will happen, you should see a cloudy blue precipitate form. Called copper carbonate. 

3. Watch demo then fold filter paper to fit inside the funnel

4. Place the funnel with the filter paper inside of it, into the mouth of a conical flask. 

5. Stir the mixture in the beaker, then carefully pour it into the funnel. 

6. Observe what happened.

Equipment:
Copper sulphate
Conical flask
Stiring rod
200ml beaker
Funnel
Filter paper

Observations:
when the two chemicals mixed it turned blue and bubbled
then when ot went through the filter paper it was completely clear.
