AQA GCSE Chemistry C2 PredictionsWatch
Any reasonable suggestions I will add to the list
Chromatography (benefits of using instrumental methods of analysing)
Titration and titration calculations
Ionic, Covalent and metallic bonding (Including giant lattices and macro-molecules)
My teacher also said that Empirical formula seems likely to come up because apparently it isn't on the new spec, and it wasn't on last year's paper. Other than that I have no idea, I am just going to spend this weekend trying to revise as much of C2 and C3 as I can!
