Manganese sulfate purification idea

bob800 - 14-6-2011 at 12:01

Looking through the Golden Book of Chemistry Experiments, I found an experiment which involves heating manganese dioxide along with sodium bisulfate to produce manganese sulfate and sodium sulfate. This, of course, would be extremely contaminated with sodium, so I was thinking of ways to separate them.

I found another experiment which involved reacting the MnSO<sub>4</sub> with sodium carbonate to precipitate manganese carbonate. I was wondering if I could filter this carbonate and then react it with sulfuric acid:

MnCO<sub>3</sub> + H<sub>2</sub>SO<sub>4</sub> --> MnSO<sub>4</sub> + CO<sub>2</sub> + H<sub>2</sub>O

Would this reaction work? It seems to me that it would, but I just want to confirm before I start experimenting.

Everything what you said is correct.

Excessive exposure of the carbonate to air may cause it to oxidize.
