2 Chemistry -- Volumetric Analysis

Calculate the mass of oxalic acid required to prepare its 250 ml of N/10 solution.

Calculate the mass of oxalic acid required to prepare its 250 ml of N/10 solution.

Solution: 

Molecular weight  of oxalic acid= 126

Equivalent weight of oxalic acid =63

Volume of solution to be prepared ,V =250ml 

Conc.of solution to be prepared, N=0.1N

Now , 

We have 

Mass of oxalic acid (g)=Equivalent weight × volume × normality ÷1000

= 63×250×0.1÷1000

1.575g
