What is a neutral solution? Give an example.

Hint: To answer this question, we first need to understand what the solution is in chemistry. A solution is a form of homogenous mixture made up of two or more components in chemistry. A solute is a material that is dissolved in another substance, known as a solvent, in such a mixture.

Complete answer:
pH - pH is a scale used in chemistry to describe the acidity or basicity of an aqueous solution. The pH of acidic solutions is lower than that of basic or alkaline solutions. The pH scale is logarithmic, indicating the concentration of hydrogen ions in a solution in reverse.
Neutral solution – Neutral solutions are those in which the concentrations of hydrogen and hydroxide ions are the same. A neutral solution could be a sodium chloride solution or a sugar solution. The pH of a neutral solution is 7. Another frequent material that has a pH of neutral is water. A neutral solution is one that is neither acidic nor basic.
So, we conclude that, Neutral substances are chemicals that do not change color when tested with litmus paper. These compounds aren't acidic or basic in any way.
Salt, ammonium chloride, calcium chloride, sodium carbonates, sodium bicarbonates, and other salts are examples.

Note:
A chemical interaction between an acid and a base is known as an acid–base reaction. It can be used to determine the pH of a solution. Several theoretical frameworks, known as acid–base theories, present diverse ideas of reaction mechanisms and their use in solving associated problems. For example, the Bronsted–Lowry acid–base theory.
