Filtration Experiment

Today in hurumanu 3, we were doing chemistry we did a filtration experiment.

Aim: 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 everything is going to go through the filter.

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.

Observations: After we put it in the funnel, it went through and turned clear.
