Question Re Sodium Bisulfite vs. Sodium Metabisulfite

[c6h6o3]

If a formula calls for X grams of sodium bisulfite, how many grams of sodium metabisulfite should I substitute for it?

 

[Ian Grant]

The same in most formula, what's sold as Bisulphite is a less pure form of Metabisulphite.

Thanks, Ian.

For most purposes you can interchange them one for one.
