Properties of hexacyanoferrote 3 ion and phenolphtalein in the experiment to show that a metal ionises in aqueous solution

That hexacyanoferrate (III) ion turns pink or purple in the presence of Fe^{2+} ions. I don't know for other metals, but we use that property in experiments of rusting iron.

The phenolphtalein only indicates the presence of OH^- ions in the solution.

And, it's "hexacyanoferrate(III)". Not "...ferrote" or "ferricyanide" (boy, what an awful name is that?).

Oops, Perito, you did a tiny typo there, lol!

'hexacyahoferrate' instead of 'hexacyanoferrate'

Its hexacyahoferrate(lll) ion

You mean an "h" isn't an "n". They sort of look the same -- and they're in the same column on the keyboard -- well, the right index finger hits them both.

Oh well.

And there he goes repeating your mistake, surely by copy-pasting what you just said :p

Well, Kevishen, is it OK?
