MERCURIC SULFATE Chemical compatibility with O-rings, rubbers, & plastics

Mercuric sulfate is a white crystalline solid with the chemical formula HgSO₄, used in various industrial and chemical applications. It is primarily employed as a catalyst in the production of acetaldehyde from acetylene, in the synthesis of other mercury compounds, and as a reagent in chemical analysis. Mercuric sulfate is also used in laboratory research and as a preservative in biological specimens. Despite its utility, mercuric sulfate is highly toxic and poses significant health risks, including neurological damage and potential carcinogenic effects. Proper handling, storage, and stringent safety measures are essential to minimize exposure. Personal protective equipment and adequate ventilation are crucial when working with mercuric sulfate.
