Iron Sulphate in sulfuric acid
« on: May 20, 2015, 05:45:12 PM »
Hi all,

I am doing very simple basic chemistry which is turning old powder of iron sulfite ack into nice chunks of green-bluish crystals.

I used very diluted sulfuric acid (at 9% or so).

What kind of process would you call this and is there a chemical formula for such process that I could study and understand better?

I realise that there's a high acidic yellow liquid forms on the top of the formed crystals, which I think it's excess of sulfuric acid.

Please do advise.

Cheers
