Chemistry: Filtering

 Filtering:

31/05

Today in science we learning about Filtering.

Separating different sized particles out a mixture. 

Not everything can be filtered, only things that can be insoluble. (You can only filter different sized particles not the same sized ones).

AIM: Make solution to separate a solution from a precipitate (precipitate is the name for a solid that forms in a liquid during a chemical reaction/

Hypothesis: I think 

Method: 

1. Pour approximately 50mL of copper sulfate 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:

Sodium carbonate Copper sulphate

Conical flask Stirring Rod

200 ml Beaker Funnel

Filter paper

Observation and discussion: 

After pouring the two liquids Copper Sulphate and Sodium Carbonate in one beaker it becomes a cloudy blue colour. The Cloudy blue liquid was Copper carbonate. After filtering the solution it became a clear liquid which became Sodium sulphate.
