Concept Introduction:
Titration: It is a quantitative analysis method used to express the concentration of acid or base present in the solution.
For an
That is,
Normality: It generally expresses the concentration of acid or base as equivalents of acid or base present in one liter of the solution.
Equivalent of Acid: Generally, 1 equivalent of ion is the number of ions which has charge of one mole. In case of acids positive charge is of interest therefore, one equivalent of acid consists of 1 mole of
Equivalent of Base: In case of bases negative charge is of interest therefore, one equivalent of base consists of 1 mole of
