Neutralization Reaction Study Guide

A neutralization reaction is a chemical reaction that occurs when an acid and a base react quantitatively to produce water and salt as products.

INTRODUCTION

What is one of a referee's most significant characteristics? An impartial referee (neutral) is essential. They can't provide one team an advantage over the other. Being neutral in chemistry implies not being an acid or a basic. A neutral material is, for instance, pure water. An acid and a base interact to generate neutral products, such as water, in several chemical processes. As you read this article, you'll see how it all transpires.

NEUTRALIZATION REACTION

A neutralization reaction is a chemical reaction that occurs when an acid and a base react quantitatively to produce water and salt as products.

Before we go further in this topic, let’s understand what acid and base are.

Acid: When an acid dissolves in water, it creates positive hydrogen ions (H ) and negative non-metallic ions. (Ions are atoms that have gained or lost electrons and have become charged.) A good example of an acid is hydrochloric acid (HCl).

Base: A base is a compound that yields negative hydroxide ions (OH-) and positive metal ions when dissolved in water.

ACID-BASE INTERACTION

Acid + base(alkali) → salt + water

Acid-Base Interaction Source

A neutral solution is formed when equal quantities of a strong acid, such as hydrochloric acid, are combined with a strong base, such as sodium hydroxide. The reaction's products don't have the properties of an acid or a base. The balanced chemical equation is shown below.

A net ionic equation is a more precise representation of chemical processes that occur in an aqueous solution. The following is the complete ionic equation for the neutralization of hydrochloric acid by sodium hydroxide:

dissociation Source

Because the acid and base both are strong, they are totally ionized and, like the NaCl generated, as a result, are recorded as ions. The sodium and chloride ions are spectator ions in the process; hence the net ionic reaction is as follows.

Net ionic eq Source

The net ionic reaction of hydrogen ions interacting with the hydroxide ion to form water simplifies all neutralization reactions of a strong acid with a strong base.

CONCLUSION

  • A neutralization reaction is a chemical reaction that occurs when an acid and a base react quantitatively to produce water and salt as products.
  • A net ionic equation is a more precise representation of chemical processes that occur in an aqueous solution.

FAQs:

1. What is the net ionic reaction for the neutralization reaction between an acid and a base?

When a strong acid, as well as a strong base, are combined, they react using the net-ionic equation below:

                      H₃O⁺(aq) + OH⁻(aq) → 2H₂O(l)

2. Which is the net ionic equation for the neutralization reaction of a strong acid with a weak base?

When a weak base and a strong acid are combined, they react as follows:

                B(aq.) H₃O (aq.) → HB (aq.) H₂O (l)

The pH of the resultant solution may be estimated by studying the equilibrium interaction of HB with water if the acid and base are equimolar.
