Question

One litre of a solution contains 18.9 g of HNO3 and one litre of another solution contains 3.2 g of NaOH. In what volume ratio these solution be mixed to obtain a neutral solution? (A) 3: 8 (B) 8: 3 (C) 15: 4 (D) 4: 15

eqHNO3 = eqNaOH (18.9/63) × 1× V1 = (3.2/40) × 1 × V2 ⇒ (V1/V2) = (201.6/756) = 4: 15

Q. One litre of a solution contains $18.9 g$ of $H N O_{3}$ and one litre of another solution contains $3.2 g$ of $N a O H$ . In what volume ratio these solution be mixed to obtain a neutral solution?

$3 : 8$

$8 : 3$

$15 : 4$

$4 : 15$

$e q_{H N O_{3}} = e q_{N a O H}$
$\frac{18.9}{63} \times 1 \times V_{1} = \frac{3.2}{40} \times 1 \times V_{2}$
$\Rightarrow \frac{V _{1}}{V _{2}} = \frac{201.6}{756} = 4 : 15$
