Blevins60 Report post Posted January 18, 2013 In my shop I found a bottle os Sodium Sulfite. I think it was for cleansing leather. The jar of Oxalic Acid I know was for cleaning. Quote Share this post Link to post Share on other sites
Beaverslayer Report post Posted January 18, 2013 Sodium sulfite (sodium sulphite) is a soluble sodium salt of sulfurous acid with the chemical formula Na2SO3. It is a product of sulfur dioxide scrubbing, a part of the flue-gas desulfurization process. It is also used as a preservative to prevent dried fruit from discoloring, and for preserving meats, and is used in the same way as sodium thiosulfate to convert elemental halogens to their respective hydrohalic acids, in photography and for reducing chlorine levels in pools.

Northmount Report post Posted January 18, 2013 Ditto what BeaverSlayer says, It is an oxygen scavenger used to preserve foods and prevent oxidation. Also used in steam boiler water treatment to reduce the residual disolved oxygen level to less than 20 ppb. Tom Quote Share this post Link to post Share on other sites
