Concept introduction:
Acid–base titration is a technique to analyze the unknown concentration of an acid or base through the known concentration of an acid and the base.
The equivalence point is the point in the acid–base titration in a chemical reaction where the number of moles of the titrant and the unknown concentration of the analyte are equal and it is used to identify the unknown concentration of the analyte.
If an anion reacts with water, it is called anionic hydrolysis. If a cation reacts with water, it is called cationic hydrolysis.
