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.
