### chloride:

Calcium chloride
* absorbs moisture from the air at a known, fixed rate
  - water vapor from the air and liquid water from the road bed
* attracts water well, sodium chloride slightly less so.
* can be corrosive to certain soft metals if left on for a period of time.
* different form of salt.
* has a high heat of solution
  - the ability to attract moisture directly from the air
* improves mushroom color and shelf life by reducing effects of bruising.
* is also an accelerator
  - an excellent economical accelerator for concrete
  - another de-icing salt
  - available as pellets or other granules, flakes, or in solution form
  - chemical compounds
  - good for pickling but bad as a supplement as it tends to irritate the stomach
  - harmless and is used all over North America for dust control and ice control
  - highly water soluble and fast-acting, but it generally is too expensive to use
  - melted at a high temperature and electrolyzed to produce calcium metal
* is mixed with salt in colder temperatures to increase the salt's melting ability
  - sodium chloride for melting ice and snow in low temperature regions
  - sold at most garden centers under the name stop rot
  - soluble in either cold or hot water
  - suggested only for tomatoes
* is the cheapest source of calcium
  - chemical most effective at extreme low temperatures
  - other product
  - unstable in the presence of water
  - used as a suspending agent in the suspension polymerization of various plastics
* is used to increase the deicing effectiveness at lower temperatures
  - protect the heart
* liquefies as it absorbs water.
* more effective ice melter than fertilizer, but it, too, can harm plants.
* prevents freezing of stored water.
* produces an exothermic reaction, giving off heat.
* remains wet at low temperatures and is itself a deicing agent.
  * ' chemical compound made of calcium and chlorine atoms. It has the formula CaCl2. It absorbs water from the air and releases heat when it is dissolved in water. It is used as a de-icer on roads to melt the ice. Calcium chloride is melted at a high temperature and electrolyzed to produce calcium metal.
* viable alternative to sodium chloride as an ice-melting agent.

Calomel
* mercury and chloride compound, usually a purgative and antiseptic.
* strong laxative while tartar is an emetic which causes vomiting.

Choline chloride
* high potency, synthetic source of choline.
* is an essential component in feed for chickens, pigs and cattle
  - ingredient necessary for the proper growth and development of animals
* vitamin of the B-complex group.

### chloride:

Ferric chloride
* Most ferric chloride is produced as a byproduct of steel pickling liquor.
* bleaching solution used on negative materials.
* gives a more controllable etch, plus it is safer than the traditional acids.
* has numerous advantages over other etchants such as nitric acid and dutch mordant.
* is best when 'seasoned' or after it has been used for etching a few copperplates
  - crystal
  - ionic compounds
  - very reactive with metals, which is one reason it was used to etch the copper
* salt which gives a clean etch to copper-based alloys.
* screening test for phenylketones.

### chloride:

Magnesium chloride
* by-product of potash production and is available as a liquid solution.
* can keep the sand from blowing to the shoulder of the road.
* great intermediate solution to reducing dust on low volume roads.
* is added to the soy milk, which separates the soy milk into curds and whey
  - another source and is applied as a liquid fertilizer
  - available in several grades, with varying amounts of water of hydration
  - less toxic than baking soda or salt
  - the newest deicing salt
  - used as a supplement to maintain adequate magnesium in the body
* neutral solid salt but hydrogen chloride is an acid gas.
* stimulates the biliary system.
* supplement for patients who are deficient in magnesium.
