Question

The formula of calcium chloride is:
A. \[Ca{\left( {Cl{O_4}} \right)_2}\]
B. \[Ca{\left( {Cl{0_3}} \right)_2}\]
C. \[CaCl{O_2}\]
D. \[Ca{\left( {Cl{O_2}} \right)_2}\]

Answer 1

Hint: Calcium chloride looks like white granular solid. Molecular weight of calcium chlorite is \[174.9816\] and its density is \[2.71\]g/cm3. It can be formed by the reaction of chlorous acid along with calcium carbonate.

Complete step by step answer:
Calcium chlorite is a white granular solid which, if formed in solution, gets crystallized as the hexahydrate. Calcium hypochlorite, hydrated, and it would be a white granular solid containing an odour of chlorine.
It is not combustible and boosts the burning of combustible materials. It is decomposed by water along with the evolution of chlorine gas and some heat.
Extended exposure to fire or heat may form in an explosion. It is then decomposed by water to form calcium hydroxide and chlorine dioxide, which is an explosive oxidizing gas.
Calcium chlorite is a strong oxidizing agent in nature. It ignites on touch with potassium thiocyanate and chemical reaction with chlorine forms explosive chlorine dioxide gas.
Reaction with ammonia generates ammonium chlorite, which is shock sensitive and explodes. If it is mixed with finely divided metallic or organic substances, the combination is highly dangerous and flammable and may be ignited even just by friction.
For now, no manufacturer is registered for the product CALCIUM CHLORITE. There is a paucity of data concerning the physical properties of this salt and they are not easily accessible.
Calcium chloride can be formed by the reaction of chlorous acid along with calcium carbonate:
 \[CaCO3\](solid) + \[2HCl{O_2}\](aq.) \[ \to \] \[Ca{\left( {Cl{O_2}} \right)_2}\]
And Here \[Ca{\left( {Cl{O_2}} \right)_2}\] is CALCIUM CHLORITE

Soo,Option D is correct as it is the resulting product.

Note:
Calcium chloride, Calcium chloride and Calcium hypochlorite are three different compounds and have few different properties. Thereby the formula is also different for all of them.
