Filtration Experiment - Hurumanu 3...

• What are we doing? Today in Hurumanu We are...

In Hurumanu 3 this week we will be doing a Filtration Experiment...

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...

Method/Steps: 

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... - What I think happened was that when the -

Sodium Carbonate-(Na2CO3) & the Copper Sulfate-(CuSO4) mixed together & I thought it wouldn't be filtered or couldn't be filtered, but I was wrong, we used a funnel with a conical flask, and we had a special filter paper to stop the Copper Sulfate-(CuSO4) from mixing the into the Sodium Carbonate-(Na2CO3) or it seperated some would say, and it was quiet satisfieying too...

Here are some of the results...
