Edexcel iGCSE chemistry, test for positive and negative ions revision notes bundle

Notes on one page each covering all the tests for anions and cations for Edexcel iGCSE chemistry, including the precipitation equations. Versions both in colour and in black and white for photocopying.

With the positive ion tests, I’ve included model equations, both complete and ionic, for the precipitation reactions, with examples for a +2 and +3 ion.

With the negative ion tests, there’s both a full and ionic equation for carbonate, sulfate and halide ion reactions to give students good models. To show the differences in formulas between compounds of metals that form +2 and +1 ions, there’s equations for both sodium and calcium carbonate too, and details of what happens if you use different acids.
