Transition metals + ammonia & NaOH - Edexcel chemistry a2

Hello guys, this is a quiz about PERCIPITATE COLOURS for reactions of transition metals with OH- and NH3, as well as in water. It is specifically suited to the Edexcel A2 unit 5 specification (chemsitry) but can be used for any. :)

N.B. the colours vary according to what textbook you use, I've used the ones in the official Edexcel textbook rather than the revision guide.
