If 20molarity of the acid solution is(a) 0.1 MmL of 0.4 N NaOH solutio

1.	If 20molarity of the acid solution is(a) 0.1 MmL of 0.4 N NaOH solution completely neutralizes 40 mL of a dibasic acid, the(b) 0.2 M(c) 0.3 M(d) 0.4 M
Answer» Volume bof NaOH=20 ml. Strength of NaOH= 0.4 N Volume of dibasic acid=40 ml. Strength of dibasic acid= ? So strength of dibasic acid=20x 0.4/40=0.2N Molarity of the dibasic acid = Normality /2. So Molarity=0.2/2=0.1 M

If 20molarity of the acid solution is(a) 0.1 MmL of 0.4 N NaOH solution completely neutralizes 40 mL of a dibasic acid, the(b) 0.2 M(c) 0.3 M(d) 0.4 M

Answer»

Volume bof NaOH=20 ml.

Strength of NaOH= 0.4 N

Volume of dibasic acid=40 ml.

Strength of dibasic acid= ?

So strength of dibasic acid=20x 0.4/40=0.2N

Molarity of the dibasic acid = Normality /2.

So Molarity=0.2/2=0.1 M
