Mercury(II) sulfate, commonly called mercuric sulfate is the chemical compound HgSO4. It is an odorless solid that forms white granules or crystalline powder. In water, it separates into an insoluble sulfate with a yellow color and sulfuric acid.
Mercury sulfate is used as a catalyst in the production of acetaldehyde from acetylene and water. Methyl mercury is produced as a side product of this conversion. Mercury-containing pollutants from this reaction are held to have caused Minamata disease in Minamata, Kumamoto prefecture, Japan.
