Mercuric chloride, also known as mercury(II) chloride or HgCl2, is a highly toxic and corrosive chemical compound composed of one mercury atom and two chlorine atoms. It exists as a white crystalline powder with a distinct acrid odor. Due to its hazardous nature, mercuric chloride has limited applications, primarily in laboratory settings for certain chemical reactions, as a reagent, and in research. However, its use is declining due to its toxicity and potential environmental harm.
