Filtration Experiment

Hello everyone, Today we are doing a filter experiment. We have a filter paper to filter the chemical we are experimenting, and no we can't drink it because we don't know if it's clean. At first, we have to put the blue transparent liquid and the name is copper sulfate. We add the transparent chemical which is sodium carbonate. when we stirred it looks like a blue opaque liquid.

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

Hypothesis: what do you think will happen...

I think that the dirty things to the chemical will stay at the filter paper and the bottom will be clear.

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: what you saw happen and why do you think it happened...

The liquid turns to transparent and there are some left blue thing left at the top of the filter paper. 

Equipment:

Sodium carbonate

Copper sulfate

Conical flask
