Filtration | Chemicals and Chaos

Welcome to another post on my blog. Today in Hur 3, Chemicals and Chaos, while doing Chemistry, we are doing an experiment about filtration, this experiment will include chemicals being separated.

Aim: To Separate a solution from a precipitate.

Hypothesis: I think that both will separate

Equipment:

1. Sodium sulfate
2. Conical flask
3. Stirring rod
4. 200ml Beaker
5. Funnel
6. 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.

Observation:

When we mixed Copper Sulfate and Sodium Carbonate, the 'carbonate' and 'sulfate' swapped and turned to;

Copper sulfate + Sodium Carbonate turned to Copper carbonate + Sodium sulfate 

The Copper carbonate stayed on the filter paper and the sodium sulfate filtered down.
