I made a poster ages ago about identifying each ion and what it is if you would like! Just go onto my resources! Good luck with your exams

You must know the colours when they burn. Positive and Negative ions. This isn't too hard make them rememberable like Potassium...Pa pa p gives purple which is lilac :p

Halides,Carbonates etc also need to be learnt.
