How many grams of a dibasic acid(mol. wt 200) should be present in100 mL of its aqueous solution to givedecinormal strength1) 1 g2) 2 g3) 10 g4) 20 g

Answer»

Equivalent wt. of dibasic acid = mol. wt/2 = 200/2 = 100 Strength = 0.1 N, m = ? , V = 100 mL then, m = EVN/1000 = (100 x 100 x 0.1)/1000 = 1gm.
