Q. Why is there no need of diluting a neutralised substance??​

Answer 1

Water and neutral solutions

Water molecules can break down into hydrogen ions and hydroxide ions.

H_{2}O(l)\rightleftharpoons H^{+}(aq)+OH^{-}(aq)

This is a reversible reaction. A small proportion of water molecules break up to form hydrogen ions and hydroxide ions. Some of these hydrogen and hydroxide ions then react together again to form water molecules.

This is called an equilibrium and is present in water and all aqueous solutions.

In water and neutral solutions, the concentration of hydrogen ions is equal to the concentration of hydroxide ions.

All acidic solutions contain more hydrogen ions than hydroxide ions.

All alkaline solutions contain more hydroxide ions than hydrogen ions.
