* Calcium hydroxide ( saturated solution known as " limewater ")

Calcium hydroxide ( slaked lime ) is used in many chemical refinery processes and is made by heating limestone at high temperature ( above 825 ° C ) and then carefully adding water to it.

* Calcium hydroxide solution ( Ca ( OH )< sub > 2 </ sub >) ( also known as limewater ) is used to detect the presence of carbon dioxide by being bubbled through a solution.

The skin is washed with water and lime ( Calcium hydroxide ), but not together.

** Calcium hydroxide, aka slaked lime, slack lime, pickling lime or hydrated lime

At a breakage site in Rome, Testaccio, close to the Tiber, the fragments, later wetted with Calcium hydroxide ( Calce viva ), remained to create a hill now named Monte Testaccio, high and more than 1 km in circumference.

Calcium phosphate is the name given to a family of minerals containing calcium ions ( Ca < sup > 2 +</ sup >) together with orthophosphates ( PO < sub > 4 </ sub >< sup > 3 -</ sup >), metaphosphates or pyrophosphates ( P < sub > 2 </ sub > O < sub > 7 </ sub >< sup > 4 -</ sup >) and occasionally hydrogen or hydroxide ions.

Calcium oxide ( lime ) is reacted with water to regenerate the calcium hydroxide used in Reaction 2:

Calcium hydroxide is caustic in the presence of water, and is very irritating to the nasal passages, so it is desirable to allow any left over calcium hydroxide to convert to calcium carbonate.

Calcium, alkalinity and other trace elements which are consumed by corals are replaced through water changes ( using natural seawater or a quality synthetic salt mix ) or the use of a calcium reactor, kalkwasser ( calcium water-calcium hydroxide mixed with pure water ) or a balanced two-part solution.

* Calcium hydroxide Ca ( OH )< sub > 2 </ sub >

Calcium ion ( Ca < sup >++</ sup >) antagonists ( Calcium channel blockers ) are used in the treatment of chronic stable angina.

Calcium ( ) is the chemical element with symbol Ca and atomic number 20.

Calcium is essential for living organisms, in particular in cell physiology, where movement of the calcium ion Ca < sup > 2 +</ sup > into and out of the cytoplasm functions as a signal for many cellular processes.

Calcium salts are colorless from any contribution of the calcium, and ionic solutions of calcium ( Ca < sup > 2 +</ sup >) are colorless as well.

Calcium has four stable isotopes (< sup > 40 </ sup > Ca, < sup > 42 </ sup > Ca, < sup > 43 </ sup > Ca and < sup > 44 </ sup > Ca ), plus two more isotopes (< sup > 46 </ sup > Ca and < sup > 48 </ sup > Ca ) that have such long half-lives that for all practical purposes they also can be considered stable.

Calcium also has a cosmogenic isotope, radioactive < sup > 41 </ sup > Ca, which has a half-life of 103, 000 years.

* Calcium arsenate ( Ca < sub > 3 </ sub >( AsO < sub > 4 </ sub >)< sub > 2 </ sub >) is used in insecticides.

* Calcium cyclamate ( Ca ( C < sub > 6 </ sub > H < sub > 11 </ sub > NHSO < sub > 3 </ sub >)< sub > 2 </ sub >) was used as a sweetening agent but is no longer permitted for use because of suspected cancer-causing properties.

* Calcium gluconate ( Ca ( C < sub > 6 </ sub > H < sub > 11 </ sub > O < sub > 7 </ sub >)< sub > 2 </ sub >) is used as a food additive and in vitamin pills.

* Calcium hypochlorite ( Ca ( OCl )< sub > 2 </ sub >) is used as a swimming pool disinfectant, as a bleaching agent, as an ingredient in deodorant, and in algaecide and fungicide.

* Calcium permanganate ( Ca ( MnO < sub > 4 </ sub >)< sub > 2 </ sub >) is used in liquid rocket propellant, textile production, as a water sterilizing agent and in dental procedures.

* Calcium phosphate ( Ca < sub > 3 </ sub >( PO < sub > 4 </ sub >)< sub > 2 </ sub >) is used as a supplement for animal feed, fertilizer, in commercial production for dough and yeast products, in the manufacture of glass, and in dental products.

* Calcium phosphide ( Ca < sub > 3 </ sub > P < sub > 2 </ sub >) is used in fireworks, rodenticide, torpedoes and flares.

* Calcium stearate ( Ca ( C < sub > 18 </ sub > H < sub > 35 </ sub > O < sub > 2 </ sub >)< sub > 2 </ sub >) is used in the manufacture of wax crayons, cements, certain kinds of plastics and cosmetics, as a food additive, in the production of water resistant materials and in the production of paints.

Calcium sulfoaluminate cements are made from clinkers that include ye ' elimite ( Ca < sub > 4 </ sub >( AlO < sub > 2 </ sub >)< sub > 6 </ sub > SO < sub > 4 </ sub > or C < sub > 4 </ sub > A < sub > 3 </ sub > in Cement chemist's notation ) as a primary phase.

* Calcium Ca < sup > 2 +</ sup >

Calcium ( Ca ) is in group 2, for it contains 2 valence electrons.

* Calcium sulfide with strontium sulfide with bismuth as activator, ( Ca, Sr ) S: Bi, yields blue light with glow times up to 12 hours, red and orange are modifications of the zinc sulfide formula.

* Calcium aluminoferrite, Ca < sub > 2 </ sub >( Al, Fe )< sub > 2 </ sub > O < sub > 5 </ sub >, a mineral found in cements

Calcium carbonate ( CaCO < sub > 3 </ sub >) is one of the common compounds of calcium.

* Calcium carbonate ( CaCO < sub > 3 </ sub >) is used in manufacturing cement and mortar, lime, limestone ( usually used in the steel industry ) and aids in production in the glass industry.

* Calcium carbide ( CaC < sub > 2 </ sub >) is used to make acetylene gas ( for use in acetylene torches for welding ) and in the manufacturing of plastics.

* Calcium chloride ( CaCl < sub > 2 </ sub >) is used in ice removal and dust control on dirt roads, in conditioner for concrete, as an additive in canned tomatoes, and to provide body for automobile tires.
