Question Q151) How many g of dibasic acid (mol. weight 200) should be present in 100 ml. of the aqueous solution to give strength of 0.1 N?




SOLUTION

Dibasic acid liberate two H+ ions which is required for calculation of Normality
For given solute molecular wt = 200
∴ Equivalent weight = 200/2= 100
Normality is given by formula

∴ w = 1 g
