Sodium hydroxide + Hydrochloric acid →

When an acid and a base react with each other then salt and water are formed.

This reaction is called a neutralization reaction.

Neutralization reactions are generally exothermic in nature .i.e. heat is released with the products.

In the above question, Sodium hydroxide (NaOH) is a base and Hydrochloric acid (HCl) is an acid.

In the reaction of NaOH with HCl, their salt NaCl and water(H₂O) will be produced. Also, some amount of heat will be released in the reaction.

Hence, the correct option is B . i.e. Sodium chloride(NaCl) + Water(H₂O) + Heat.
