Black sulphide
WebOVERVIEW. Mercury (II) sulfide (MER-kyuh-ree two SUL-fide) occurs in two forms, red and black. Red mercury (II) sulfide, commonly known as cinnabar, begins to change color when heated to temperatures of about 250°C (500°F) and converts to the black form at 386°C (727°F). If heated further, it sublimes (changes directly from a solid to a gas ... WebIt is a strong base. Bisulfide solutions are corrosive and attack the skin.
