Cadmium sulphide
CdS, a compound with two forms; orange, insoluble in water, used as a pigment, and also known as orange cadmium; light yellow, hexagonal crystals, insoluble in water, and also known as cadmium yellow
Calcium arsenite
Ca3(AsO3)2, white granules that are soluble in water; used as an insecticide.

Caesium
a soft silvery highly reactive element of the alkali metal group. It occurs in several silicate minerals, including pollucite (CsAlSi2O6) Caesium is used in photocell, as a catalyst, in the caesium atomic clock, and recently in ion-propulsion systems for spacecraft

Caesium chemistry
caesium is an element of group I, electronic configuration 6s-1. It forms a single series of components in the +1 oxidation state; most compounds are predominantly ionic. It also forms a series of lower oxides, e.g., Cs7, O, Cs11O3 containing cluster cations
Calcium acetylide
Calcium dicarbide.
Calcium arsenate
Ca3(AsO4)2, an arsenic compound used as an insecticide to control cotton pests.

Caesium chloride (CsCl)
a typical alkali halide obtained from CS2CO3 and HCl. Each ion has a coordination number eight.
Calamine
a zinc mineral (ZnCO3 or zinc silicate). It is used in medicine as a lotion or powder for sunburn.

Calcination
the formation of a calcium carbonate deposit from hard water.
Calcite
a mineral form of calcium carbonate occurring in lime-stone and marble.
Calcium
a chemical element, symbol Ca, atomic number 20, atomic weight 40.08; used in metallurgy as an alloying agent for aluminium-bearing metal, as an aid in removing bismuth from lead, and as a deoxidizer in steel manufacture, and also used as a cathode coating in some types of photo rubes

Calcium bisulphate
Ca(HSO3)2, a white powder, used as an antiseptic and in the sulphite pulping process.
Calcium bromide
CaBr2, a deliquescent salt in the form of colourless hexagonal crystals that are soluble in water and absolute alcohol.
Calcium carbide
CaC2, an alkaline earth carbide obtained in the pure form as transparent crystals that decompose in water; used to make acetylene gas.
Calcium carbonate
CaCO3, white rhombohedrons or a white powder; occurs naturally as calcite; used in paint manufactures, as a dentifrice, as an anticaking medium for table salt, and in manufacture of rubber tyres.
Calcium chlorate
Ca(ClO3)2.2H2O, white monoclinic crystals, decomposed by heating.
Calcium chloride
CaCl2, a colourless, deliquescent powder that is soluble in water and ethanol; used as an antifreeze and as an antidust agent.
Calcium chromate
CaCrO4.2H2O, yellow, monoclinic crystals that are slightly soluble in water; used to make other pigments.
Calcium cyanamide
CaCN2, in pure form, colourless rhomobohedral crystals, the commercial form being a gray material containing 55-70% CaCN2; used as a fertilizer, weed killer, and defoliant.
