Mercury happens as salts for example mercuric chloride (HgCl2) and mercurous chloride (Hg2Cl2), the latter also referred to as calomel. As they tend to be more soluble in h2o, mercuric salts tend to be far more acutely toxic than mercurous salts. Their larger solubility allows them be far more commonly absorbed from the gastrointestinal tract.
