Hey,
Do I need to know the colours of complexes of transition metals besides
Fe3+, Fe2+, Cu2+, and Al?

Because ive seen questions about Cr and Co but its not even in the textbook.

Thanks

The cobalt colours have been scrapped in the new spec. There is a note about it here, but nothing about chromium.

However, the new spec doesn't mention that chromate colours at all so that's probably gone too. The vanadium colours mentioned in the above file are new so you'll have to learn those.
