Mercuric chloride, or also known as Mercury (II) chloride, is a chemical compound which consists of mercury and chlorine that has the chemical formula HgCl2. Mercuric chloride is an odorless white crystalline solid. It has the melting point of 277°C and boiling point of 304°C.

This chemical is slightly soluble in water. Despite its tendency to sublime, Mercuric chloride does not exist as a salt composed of discrete ions, but rather the chemical’s salt is composed of linear triatomic molecules.

Uses of Mercuric chloride

Although mercuric chloride has several uses to name, the some of the uses were only applied historically. Some of mercuric chloride uses can be seen as listed below.

  • Chemical reagent: Mercuric chloride is sometimes used to form an amalgam metals like aluminum.
  • Stabilizing agent
  • Historic purposes in photography: Mercuric chloride as a photographic intensifier in the 19th It was used to produce positive pictures in the collodion process of photography.
  • Historic purposes in preservation: Mercuric chloride, in preservation purposes, is used to preserve anthropological and biological specimens during the late 19th century to early 20th Those specimens were dipped in or painted with the mercuric solution. The preservation with mercuric chloride was done to prevent the specimens’ destruction that may be caused by moths, mites, and molds. The chemical is also used in wood preservation.

  • Central nervous system depression (which leads to sensory and memory disturbance)
  • Kidney damage
  • Nephrotic syndrome (which leads to proteinuria): Nephrotic syndrome is a kidney disorder which causes the body to excrete too much protein in the urine.
  • Proteinuria: Proteinuria is a condition where there is an excess presence of protein in the urine.
  • Acute renal failure
  • Ataxia: Ataxia is a condition where a person loss full control of their bodily movement.
  • Hyperemia of optic nerve heads
  • Retinal vein occlusion (RVO): This effects is the rarest effects among other health risk of Mercuric chloride. Retinal vein occlusion or RVO is a blockage of the small veins that carry blood away from the retina.

First Aid Measures of Mercuric chloride’s Health Effects and Act of Prevention

If you happen to get exposed to Mercuric chloride, you can minimalize the health risks that may occur. The first aid measures that will be explained is divided by route of exposures. First aid measures of Mercuric chloride exposure can be seen as listed below.

  • Inhalation: Inhale fresh air as soon as you can and rest for a while. Get into half-upright position. Seek for medical attention. If the victim is unconscious, move the victim to fresh air. Check the victim’s vital sign (which includes pulse and respiratory rate). Provide CPR or artificial respiration if needed.
  • Skin contact/absorption: Remove clothes that are contaminated. Rinse the contaminated area of the skin with plenty of water and soaps for at least 15 minutes. Ask for immediate medical attention.
