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
Other Properties
Soluble in water, ethanol. Insoluble in ether.
Deliquescent point at 20C is 23.3 % RH (see saturated salt solutions)
