science-Filtering

Hello today in science we are doing filtering and a little experiment to do with filtering. filtering- is separating different size particles out of a mixture  based on there size. Can all mixtures filtered? no only insoluble particles... If it has dissolved into the liquid it has to be separated a different way. 

experiment:

make a mixture then separate it...

chemical liquids: 

copper sulfate- light blue, liquid, transparent.

sodium carbonate- colourless, liquid, translucent.

what I think will happen...

I think it might separate is you can make the filter right it will most likely all separate but if you don't have it right i might not separate probably. With the liquids I think they will combined and the light-ish blue with the clear, it might become a lighter blue. 

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.

what happened: It become dark blue and cloudy (Opaque) i don't know why it happened. When we separated it become copper carbonate we the come together it becoming a small solid (blue sludge-precipitate) then when we filter it become clear because of sodium sulfate.
