In the table, there are so many colours of metals and their oxidation states. Unless you are planning or have taken A2, which ones are the ones you need to know off by memory?

Thanks.

Btw, are you following Edexcel(Old spec), I told as per the Old specification as I am an International Student so if you follow this specification then you need to know the above mentioned ions and their colours.
