WebConsider an acid-alkali titration. V 1 cm 3 is that of an acid solution of normality N 1 required to neutralize V 2 cm 3 of a base of normality N 2. We know that 1000 cm 3 of 1N acid solution contains acid = 1 gram equivalent. V 1 cm 3 of 1N acid solution contains acid= V 1 /1000 gram equivalents. Thus number of gram equivalents of acid in V 1 ...

The mole fraction or molar fraction (xi) is defined as the amount of a constituent (expressed in moles), n i, divided by the total amount of all constituents in a mixture (also expressed in moles), n tot: x i = n i n t o t. The sum of all the mole fractions is equal to 1: ∑ i = 1 N n i = n t o t; ∑ i = 1 N x i = 1.
