Silver(I) chromate (Ag2CrO4)-Powder

Silver(I) chromate (Ag2CrO4)-Powder introduce:

Characteristic




Silver chromate (Ag2CrO4) is a brown-red monoclinic crystal and is a chemical precursor to modern photography. It can be formed by combining silver nitrate (AgNO3) and potassium chromate (K2CrO4) or sodium chromate (Na2CrO4). 




Formula: Ag2CrO4

Formula weight: 331.73g/mol

Appearance:brown-red powder

Density 5.63g/cm3

Sensitivity: Light Sensitive. Ambient temperatures.

Form: Powder

Solubility: Slightly soluble in water. Soluble in HNO3 and ammonia




Application




The use of the compound itself in the laboratory is rather limited, although its formation is used to indicate the endpoint in the titration of chloride with silver nitrate in the Mohr method of argentometry.
