Filtration

Keyword:

Filtration - The separation of different sized particles 

Can all mixtures be filtered - No only insoluble particles can

Aim:

make a mixture and then separate it 

Equipment:

Copper sulphate

Sodium carbonate

stirring rod

200ml beaker

funnel 

filter paper

Conical flask

Hypothesis:

I believe when we try to filter them they will separate due to the particles in 1 chemical having slightly bigger particles but there still may be some residue in the filtered product

Method: 

1. Pour approximately 50mL 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.

Conclusion: 

When the chemicals were first combined the resulting mixture turned blue and murky then when filtered it turned clear with a light amount of residue and a slightly blue tint

The reaction between the 2 made the copper sulphate into copper carbonate and vies versa with the sodium the copper carbonate turned into the blue sludge that did not filter
