Interpretation:
The molarity and normality of solution prepared by dissolving 5 g of
Concept Introduction:
Moles: One mole is equivalent to the mass of the substance consists of same number of units equal to the atoms present in
Normality: It generally expresses the concentration of acid or base as equivalents of acid or base present in one liter of the solution.
Molarity: The concentration for solutions is expressed in terms of molarity as follows,
The normality for any acid or base equals the molarity times of the number of
Equivalent of Acid: Generally, 1 equivalent of ion is the number of ions which has charge of one mole.
Equivalent of Base: In case of bases negative charge is of interest therefore, one equivalent of base consists of 1 mole of
