), which is a form of Chalk, marble and limestone. Calcium carbonate is largely insoluble in water, however, it is quite soluble in water containing dissolved carbon dioxide, combining with it to form a bicarbonate. Such a reaction on limestone results in the formation of stalactites and stalagmites in caves.
Reaction with Oxygen
Calcium oxide is a chemical compound containing calcium and oxygen. Calcium burns quite vigorously in oxygen and strong heating is required to make it burn. It gives a dull red flame to produce a white powder of calcium oxide.
Calcium + Oxygen —> Calcium oxide
Calcium Reaction with Dilute Acids
Examples of Calcium Reaction with Dilute Acids are as follows:
- It reacts with dilute nitric acid to give calcium nitrate and hydrogen gas
- It reacts with dilute sulphuric acid to give calcium sulfate and hydrogen gas
- It reacts with dilute hydrochloric acid to give calcium chloride and hydrogen gas
Calcium Water Reaction
Colorless gas bubbles, indicative of hydrogen gas, are produced when calcium is added to water. This process produces a milky suspension as the hydroxide is only slightly soluble in water.
Calcium + Water —> Calcium hydroxide + Hydrogen
Some examples of a chemical reaction include most commonly burning, fermentation, tarnishing and rusting. There are several different types of Chemical reaction which have been detailed below:
- Substitution reaction
- Double displacement reactions
- Acid-base reaction
- Combustion reaction
- Combination reaction
- Decomposition reactions
