Question

What will be the normality of a solution obtained by mixing 0.45 N and 0.60 N NaOH in the ratio 2: 1 by volume: (A) 0.4 N (B) 0.5 N (C) 1.05 N (D) 0.15 N

Tardigrade Admin · Accepted Answer

meq. of NaOH = 0.45 × 2V + 0.6 × V Total volume = 3 V ∴ N × 3V=0.45 × 2V + 0.6V; ∴ N = 0.5

Q. What will be the normality of a solution obtained by mixing $0.45$ $N$ and $0.60$ $N$ $N a O H$ in the ratio $2 : 1$ by volume:

$0.4$ $N$

$0.5$ $N$

$1.05$ $N$

$0.15$ $N$

meq. of $N a O H = 0.45 \times 2 V + 0.6 \times V$
Total volume $= 3 V$
$∴ N \times 3 V = 0.45 \times 2 V + 0.6 V$ ;
$∴ N = 0.5$
