Is sodium metabisulfite the same as sodium bisulfite?
sodium bisulfite is an old name for sodiumhydrogensulfite NaHSO3 and does not exist in solid form. In the solid form the formula is Na2S2O5 which is Sodium disulfite and this has the old name sodium metabisulfite.
What happens when sodium metabisulphite is dissolved in water?
When introduced to water, sodium metabisulfite liberates sulfur dioxide gas which has a very pungent and unpleasant odour. This gas can also lead to respiratory problems in humans.
What is metabisulphite powder?

Is sodium metabisulfite and potassium metabisulfite the same?
The only difference between sodium metabisulfite and potassium metabisulfite is that they will leave a residual trace of either sodium or potassium.
