Neutralisation
Neutralisation
6.7
Neutralisation
Definition of Neutralisation
The reaction of an acid with base or alkali that forms salt and water.
Examples of Neutralisation Reaction
\(HCl + NaOH \rightarrow NaCl+H_2O\)
\(H_2SO_4 + CuO \rightarrow CuSO_4 + H_2O\)
\(2HNO_3 + Ca(OH)_2 \rightarrow Ca(NO_3)_2 + H_2O\)
Definition of Titration Method
A quantitative analysis method to determine the volume of acid needed to completely neutralise a given volume of alkali and vice versa.
Acid-Base Titration
In acid-base titration, a solution of known concentration is slowly added from a burette into a conical flask that contains a volume of alkali of unknown concentration.
Titration stops as soon as the acid-base indicator changes colour.
The point in the titration at which the acid-base indicator changes colour is known as the end point.
