Any chemistry paper 3 predictions for a level (edexcel) Thought everyone could say what they think is going to come up/ hasn't come up yet and then collectively make a list

probably looking at a lot of redox ii, transition metals (colours and ligands/reactions maybe), titrations, acid/base equilibria, and organic synthesis.

Wasn't there quite a lot of acid/base equilbria in paper 1? It had buffers, titration curves etc. IR and mass spec haven't come up yet.

true, i forgot about the curve in paper 1. although we haven't had any calculations from that topic yet. and definitely- i feel like they're gonna hit us with tons of NMR and mass spec.

Wasn't there a buffer calculation and something about the ionic product if water on paper 1 for topic 12 already? Plus the buffer in the blood

Yes, there was some Gibb's energy stuff on there and a Born-Haber cycle. My teacher suggested maybe finding the order of reaction wrt a reactant from a concentration-time graph.
