Calcium, as a metal, is used as a reducing agent in preparing other metals and as an alloying agent. Calcium compounds are widely used to build stone, to make cement, as a soil conditioner and in water treatment to reduce acidity. It is also essential to all living things because it is the main component of bone.
Calcium is the fifth element and the third-most abundant metal in the Earth’s crust. The distribution of calcium is very wide. In fact, it is found in almost every terrestrial area in the world. It is not found alone in nature, but it occurs abundantly as limestone, gypsum, fluorite and apatite. This element is essential for the life of plants and animals. In fact, it is present in the animal’s skeleton, in teeth, in the egg’s shell, in the coral and in many soils. It is also contained in the soft tissue, in fluids within the tissue and in the structure of every animal’s skeleton.
Calcium is the most abundant metal in the human body. It is the main constituent of bones and teeth, and it has key metabolic functions. It is sometimes referred to as lime. It is most commonly found in milk and milk products, but also in vegetables, nuts and beans. It also assists the functions of nerves and muscles.Learn More

Calcium carbonate produces a weak chemical reaction with vinegar, which is an acetic acid, by releasing carbon dioxide. A simple experiment that demonstrates the reaction is to soak an egg, which has a calcium carbonate shell, in vinegar, which completely dissolves the shell in a matter of days.Full Answer >
When sulfuric acid is added to calcium nitrate, nitric acid and calcium sulphate are produced. This is illustrated by the equation Ca(NO3)2(aq) + H2SO4(aq) = CaSO4(s) + 2 HNO3(aq).Full Answer >
