kia ora today we are doing a experiment we are filtering using liquids. Filtering is separating different sized particles out of a mixture. Can all mixtures be filtered? No only insoluble particles. We are going to be making a mixture then separate them. We are going to be using copper sulfate copper sulfate is light blue it is a liquid and it is transparent. We are also going to be using sodium carbonate this chemical is colorless and also is a liquid but this one is translucent. I think that when we filter them they will both be the same color but different chemicals.
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.
When I put the chemicals together the went from being transparent and translucent to opaque then when it went through the filter paper it was clear. The two chemicals reacted together so the blue sludge at the top was copper carbonate and at the bottom there was sodium sulfate.
