I added some shavings of Magnesium metal to a solution of KNO3 I bought as stump remover. These started to react with colorless gas being
formed and I thought the KNO3 might be a catalyst for:
Mg + 2H2O = Mg(OH)2 + H2
However, I found that eventually with enough Magnesium added the reaction stops. I don't know exactly what is occurring but I would guess it could be
something like:
Mg + KNO3 = MgO + KNO2
But this reaction doesn't form any gases.
Can anyone verify this reaction or propose the actual one?

Nevermind I checked the SDS(I'm surprised I didn't check it before) and it is sodium metabisulfite. I would still be interested to see what the
reaction would be as I am not familiar with this chemical.

Mg + Na2S2O5 + H2O >> MgSO3 + Na2SO3 + H2 (g)
