Filtration

Hi everyone! Welcome to another post today during science we did an experiment on filtration and some other topics about mixing and separating. The things we learned today were Solvent, Solute, Solution, Filtration,  Filtrate, Mixture and Solubility. We needed to know these key words for our experiment, so that we can understand what we are doing and what is happening to the mixture during filtration. 

Aim: Our aim was to separate a solution from a precipitate, which is the name of 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

Method:

1. Pour 50ml of Copper Sulfate into the beaker. 
2. Add the same measurement of Sodium Cabornate solution. 
3. Fold the filter paper so that it can fit inside the funnel. 
4. Place the funnel with the filter paper inside the conical flask. 
5. Stir the mixture that was in the beaker and then carefully pours in the funnel. 

Observation: 

When the Copper Sulfate (blue transparent liquid) and the Sodium Carbonate (transparent liquid) were 2 mixed it had a chemical reaction. The mixture was more opaque and it was no longer transparent, it looked like the colour cyan. 

When we poured the mixture into the funnel with the filter paper and it filtrated the solution it came out with a clear solution similar to water (but it isn't water). The solution looked more chunky and looked as if it had something in it. 

Discussion: 

I think the solution came out as a clear colour because of the chemical reaction where we mixed the Copper Sulfate and the Sodium Carbonate. As I said in my observation it looked like it had chunks in it and I thought that maybe it was the cause of the outcome of the filtration. To follow with that statement because there were solids in the mixture it got caught in the filtration paper and then the liquid was then filtrated out to the conical flask.
