Chromic acid (H2CrO4) is a chromium oxoacid that contains hexavalent chromium and acts as an oxidising agent. It is formed by acidifying solutions that contain chromate and dichromate anions or by dissolving chromium trioxide in sulfuric acid. It is used in chromium electroplating, aluminium anodizing, metal cleaning and leather tanning, and as a textile mordant. Other uses include ceramic glazes, coloured glass and the etching of plastics.
