Description of Potassium Chromate
Potassium chromate (K2CrO4) is a yellow solid. It is a potassium salt produced by chromic acid and is employed for the identification of chloride ions. The chromium in potassium chromate is hexavalent and is classified as carcinogenic. Inhalation or ingestion may result in cancer. Potassium chromate is utilised as an anti-corrosion agent for metals, in the production of chromates, as an oxidising agent, and as an etching agent for printing and dyeing processes, ink, pigment, enamel, and metal corrosion protection, among other applications.
Stanford Advanced Materials (SAM) is a supplier of potassium chromate on a global scale. The company has manufactured and distributed the compound for over 20 years, thereby ensuring a reliable supply.
