SILVER CHROMATE Chemical Properties,Usage,Production

Chemical Properties

crystalline powder

Physical properties

Red monoclinic crystals or brownish-red powder; density 5.625 g/cm³; insoluble in water; soluble in nitric acid, ammonia and solutions of alkali cyanides and chromates.

Uses

Catalyst for formation of aldol from alcohol; formed at end point of Mohr titration of halides.

Preparation

Silver chromate is prepared by slowly adding a solution of potassium chromate to a solution of silver nitrate:
2Ag+ (aq) + Cr₄O^2- (aq) → Ag₂CrO₄ (s)
The precipitate is washed with hot water.

Purification Methods

Wash the red-brown powder with H2O, dry it in a vacuum, then powder well and dry again in a vacuum at 90o/5hours. Its solubility in H2O is 0.0014% at 10o. Store it in the dark. [Cardillo & Shimizu J Org Chem 42 4268 1977.]
