Question

What is the correct formula for barium chloride $ ? $

Answer 1

Hint :Before writing the formula for barium chloride. First understand how to get barium chloride and some important properties of barium chloride. Then write the formula for barium chloride and how it reacts with other molecules.

Complete Step By Step Answer:
Barium chloride is an organic crystal compound that is made up of barium cations $ \left( {B{a^ + }} \right) $ and chloride anions $ \left( {C{l^ - }} \right) $ . It is one of the most common water-soluble salts of barium. It is in white colour, toxic and it shows a yellow-green coloration when it is burned or under flame. Since barium chloride is neither an acid nor a base. It is a neutral crystal salt meaning it is an alkali.
The correct formula of barium chloride is $ BaC{l_2} $ .
The density of barium chloride is $ 3.856\;g/c{m^3} $ . Its molecular weight is $ 208.23\;g/mol $ . Its melting point and boiling point are $ {962^o}C $ and $ {1560^o}C $ respectively.
When barium chloride is heated, it is soluble in water, slightly soluble in some acids, for example sulfuric acid, insoluble in acetone, ethanol etc.

Note :
Note that barium chloride is an anion and it has a negative charge. Barium chloride is mainly used in the purification of brine solution in caustic chlorine plants in industry areas and also in the manufacture of heat treatment salts, case hardening of steel, in the manufacture of other barium slats.
