Filtration

Today in hurumanu 3, for 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 that 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 following our method we finally got the results and it wasn't what we expected. After pouring the mixture into the funnel, it went through and it came out clear.
