Description

White, deliquescent crystals often used for humidity control. Potassium acetate is used as a dehydrating agent, textile conditioner, an Ice melter, and as an additive in crystal glass. In a closed environment, a saturated solution of potassium acetate will form an equilibrium at a relative humidity of about 23% (20C).

Synonyms and Related Terms

foliated earth of tartar; acetate of potash

Risks

Combustible.
