), 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.
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.

Reaction with Dilute Acids
Examples of Calcium Reaction with Dilute Acids are as
- It reacts with dilute nitric acid to give calcium nitrate and hydrogen
- It reacts with dilute sulphuric acid to give calcium sulfate and
- It reacts with dilute hydrochloric acid to give calcium chloride and
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

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
- Combustion reaction
- Combination reaction
- Decomposition reactions
