Filtration Experiment

Filtration Experiment

In hurumanu 3 today we are going to be doing a Filtration Experiment, we have been learning about particles and today we are going to try and filter them.

Hypothesis: What do you think will happen

Aim: To separate a solution from a precipitate (precipitate is the name for a solid that forms in a liquid during a chemical reaction)

Equipment:

Sodium carbonate

Copper sulfate

Conical flask

Stirring Rod

200mL Beaker

Funnel

Filter paper

Hypothesis: What do you think will happen?
I don't think that much will happen I think it will just stay blue but im really hoping something interesting will happen.

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 and Discussion:

When we poured the liquids into the funnel it was a very ultra blue type colour but when it started filtering it turned into a clear colour which was the sodium carbonate we mixed into the copper sulfate , on the filter paper there was a blue residue that we could see.

All of the blue colour got filtered out and left behind a clear liquid.
