Question

If 20 mL of 0.4 N NaOH solution completely neutralizes 40 mL of a dibasic, the molarity of the acid solution is (A) 0.1 M (B) 0.2 M (C) 0.3 M (D) 0.4 M

Tardigrade Admin · Accepted Answer

meq. of NaOH = meq. of acid; 20 × 0.4 = 40 × N; ∴ N= 0.2 or M= 0.1

Q. If $20 m L$ of $0.4 N N a O H$ solution completely neutralizes $40 m L$ of a dibasic, the molarity of the acid solution is

$0.1 M$

$0.2 M$

$0.3 M$

$0.4 M$

meq. of $N a O H = m e q$ . of acid;
$20 \times 0.4 = 40 \times N;$
$∴ N = 0.2$ or $M = 0.1$

Q. If 20mL of 0.4NNaOH solution completely neutralizes 40mL of a dibasic, the molarity of the acid solution is

0.1M

0.2M

0.3M

0.4M
