Science - Filtering

Hello today in science class we are learning about filtering.

Filtering is about filtering things and separate different sizes particles. Filtering only works with only particles of different sizes. Today's experiment is we are making a mixture and separating it. The 2 chemical we are using is copper sulfate, a light blue liquid, and the other liquid is sodium carbonate. 

Hypothesis:

I think that when we mix the 2 chemicals the color will be light blue and I think will separate. 

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 add the 2 chemicals it went dark blue and become cloudy. When we put it through the filter the liquid went clear and see through. The sodium sulficate was the clear liquid in the clinical flask and the copper carbonate was the solid blue cloudy bit on the top that didn't filter through.
