Filtration Experiment - Science

 Aim: Separate a mixture we have made using filtration.

Hypothesis: I think that it will just mix the two colours together and I think they wont separate because they are both liquid. I also think that when the copper sulfate goes through the filter paper and the funnel the colour will change from blue to clear. The things we are mixing in copper sulfate which is blue and sodium carbonate which is clear. I think it will go pale blue because one of the liquids are different and different coloured. Since they are both liquids they will not split and both liquids will go through the filter 

Equipment:

Copper sulfate

Conical flask

Stirring rod

200mL, beaker

Funnel

Filter paper

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: When we mixed the the copper sulfate and sodium carbonate the mixture flips and is now copper carbonate and sodium sulfate. Because of this happening the copper carbonate now is insoluble and wont dissolve making it a solid that wont dissolve. 

Since we now have a solid in a mixture some part of it wont go through the filter making it clear in the beacon after the blue is filtered out.
