Mercurous chloride (also known as Calomel) is an odorless white solid that sinks in water. It is used as reference electrodes in electrochemistry. It was once used as a fungicide and as a treatment for intestinal worms. It is also used in photochemistry to calculate the number of photons in the light beam. It is toxic but considered to be less dangerous due its low solubility in water. It is also found in pH meters. In analytical chemistry it is used in the detection, estimation, separation and recovery of metals like gold, silver, platinum and palladium.
