Mixing and Separating

For today's 2 hours of science, we are doing two in one experiment! We are going to make our own mixture then we are going to create a filter to filter the mixture we are creating.

KEYWORDS -  

solvent - The thing doing the dissolving (Liquid)
solute -  The thing being dissolved (Solid)
Solution - The mixture that has formed
filtration - Separates particles based on size
filtrate - liquid after it has been filtered
mixture - 2 or more substances together
solubility - ability to dissolve

AIM - 
To separate a solution from a precipitate (Precipitate is the name for a solid that forms in a liquid during a chemical reaction.)

MATERIALS - 

Copper sulfate
Sodium carbonate
Beaker
Funnel
Filter paper
Conical flask
Stirring Rod 

METHOD - 

1 - Add 50ml of sodium carbonate + copper sulfate into your beaker.

2- Mix the two liquids together with your stirring rod.

3- fold your filter paper into quarters and fold it out so it is in a funnel shape and slip it into the funnel. 

4 - Place your funnel and filter paper into the conical flask 

5- Pour in your mixture from the beaker and watch the magic happen! 

RESULTS - 

We added 50ml of each (Sodium Carbonate which was clear and colorless + copper sulfate still clear but had a twinge of light blue) They are both clear but when mixed together become an opaque blue. When the mixture was filtered the filtrate came out clear and colorless just like how the sodium carbonate had started off. What was left were the bigger particles that couldn't get through the filter paper and had become solid. The particles that remained on the top became a very gluggy texture that reminded me of glue, which was unlike the liquid filtrate. Though the remains on the top were really chunky, almost a slimy texture the filtrated mixture came out in a steady flow of drips that joined the transparent liquid down the bottom. The filtrate was the sodium carbonate and the blue solid was the copper sulfate.
