An example of an exothermic reaction is:
the dissociation of an electrolyte in water.
the dissociation of a salt in water.
the neutralization of an acid by a base.
the melting of ice.

Exothermic refers to a RELEASE of energy through a reaction(usually chemical). When salt dissociates, polar water molecules pull apart ions, releasing energy.

The neutralisation of an acid by a base is an example of exothermic reaction ,therefore the correct answer is option C.

What is an exothermic reaction?

It is a type of chemical reaction in which the large amount of energy is released when two or more than two reactant react with each other.

This type of chemical reaction accompanied with extra energy released in the product side while on the other hand the endothermic reactions are the chemical reaction in which the heat energy is utilised on the reactant side for the completion of chemical reaction.

The difference between exothermic and endothermic reaction is mainly either from the release of heat energy on product side or consumption of energy on the reactant side.

There is release of energy when acid react with base during the neutralisation reaction of an acid by a base, therefore it is one of the example of the exothermic reaction,Hence the correct answer for the given problem is option C.
