Hello readers! In today's blog we will be doing a little science experiment about filtering in bio, we will also be learning about this and possibly researching about it! Some of the things we might do are recording the data on our blog and put the things we've learned in during and after the experiment.
Filtering - Filtering is separating different sized particles in a mixture (Filtering things based on their size)
Not everything can be filtered ( If the particles are the same size you cant separate them) It only works if 2 particles are different sizes.
Today's experiment/goal will be, to make a mixture and separate it. The 2 liquids listed below will be the things we are using/filtrating today.
Equipment -
Copper Sulfate -
Light blue
Liquid
Transparent
Sodium Carbonate -
Colourless
Liquid
Translucent
Hypothesis - In my opinion I think the 2 liquids will not be able to get separated because they're both liquids, usually you can't separate liquids together because it is insoluble since they are the same size. Although, both liquids might turn blue due to the colour of the other 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).
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.
Observation -
The first thing we did was mixing the 2 liquids together with a clear mixing tool, as we stirred it faster and faster it turned foggy blue. It didn't look very clear anymore. After we've mixed it, we soon put it through the filtrating paper to see how it would react. The colours ended up changing into a clear liquid mixture, so the two other liquids were put mixed in with each other and was able to make that type of mixture. The ending mixture turned into copper carbonate.
Copper carbonate -
Blue sludge ( Precipitate )
Sodium Sulfate - clear liquid
