C3.4 Further Analysis and Quantitative Chemistry
This is a big topic. It covered ion tests and titration. Titration could be the big maths question or the 6 marks question. Ion tests are likely to come up as problem solving questions. There are lots of tricky topic here.
Here are all the videos you'll need...
Testing for sulfate ions
Testing or carbonate ions
Testing for positive ions
Flame tests for positive ions
Testing for halide ions
