Question

The compound calcium chloride is a strong electrolyte. Write the reaction when solid calcium chloride is put into water:

Answer 1

Mixing calcium chloride with water is an exothermic reaction, which means that the combination of the two substances releases heat. Thus, when you add calcium chloride to water, the solution heats. When adding calcium chloride to water, hydrochloric acid and calcium oxide form.

Hence the reaction is-

CaCl₂(s) --> Ca²⁺(aq) + 2Cl^-(aq)
