Chapter 19.4, Problem 43LC

Interpretation Introduction

Interpretation : The type of reaction that is neutralization reaction is to be identified and explained.

Concept Introduction : A chemical reaction is a reaction where the reactants are converted to products. There is a bond break in the reactants and bond formation in the products. The chemical reaction leads to the new substance formation.

Answer to Problem 43LC

The neutralization reactions are a type of double displacement reaction where the acid and base react to give the salt.

Explanation of Solution

They are five types of chemical reactions based on the nature of the rearrangement of atoms.

1. Combination reactions
2. Decomposition reactions
3. Single displacement reactions
4. Double displacement reactions
5. Combustion reactions

The double displacement reaction is divided into two. They are:

1. Precipitation Reactions
2. Neutralization Reactions

The kind of displacement reaction where acid and base react to give salt and water. Such reactions are called a neutralization reaction.

Example: When sodium hydroxide reacts with hydrochloric acid, sodium chloride and water is formed. The salt formed is neutral and soluble in water.

  $\text{NaOH}(aq)+\text{HCl}(aq)\to \text{NaCl}(aq)+{\text{H}}_{\text{2}}\text{O}(l)$
