GCSE C2 CHEMISTRY ADDITIONAL EDEXCEL QUIZ
This resource doesn't cover one specific topic or the whole of C2. I have made flash cards (not electronically) and when filtering through them I have made this quiz to help me remember all the flash cards I didn't know. Please don't take this as a staple revision source - this only has a few random pieces from different topic areas.

2. How do scientists use chromatography to identify colourless substances like amino acids and sugars>
- Spraying the paper with universal indicator so the colourless substances change colour
- Setting it on fire with a bunsen burner
- Spraying the paper with a locating reagent which reacts with the invisible spots to produce a colour
- Filtering it and seeing which colours are left
3. How do you test for sulfate ions?
- Placing the sulfate ion solution in an oxygen tank. It will freeze is sulfate ions are present.
- Adding HCl and barium chloride solution. If a white precipitate forms it contains sulfate ions. The precipitate will be barium sulfate.
- Adding phosphate ions and silver nitrate. The metal will run off and fizz, producing a hydrogen. This shows sulfate ions are present.
- Adding sulfuric acid and barium chloride solution. A displacement reaction will occur to show sulfate ions are present.
4. How do you test for chloride ions?
- Add silver nitrate, if a precipitate forms it contains chloride ions.
- Bubble it through limewater - if a blue precipitate is formed it contains chloride ions.
- Dip a nichrome wire in acid and dip it in the substance, put it in a bunsen burner and the flame will turn blue if chloride ions are present.
- Add water sterilising tablets. If it turns cloudy, chloride ions were present, as chlorine is present in a swimming pool.
