Step 1- Introduction
Titration is an experimental method of analysis where a solution of known concentration is titrated with a solution of unknown concentration. Acid -Base titration involves determining the unknown concentration of an acid or a base by neutralizing it with another base or acid of known concentration.
The titration of a weak base and a strong acid forms a salt. Now in case of salt formation the pOH is calculated by using the following equation :
