Question

The normality and volume strength of a solution made by mixing 1.0 L each of 5.6 volume and 11.2 volume H 2 O 2 solution are : (A) 1 N , 5.6 vol (B) 1.5 N, 5.6 vol (C) 1.5 N , 8.4 vol (D) 1 N , 8.4 vol

Tardigrade Admin · Accepted Answer

1 N =5.6 vol ⇒ Normalities of two solutions are 1 N and 2 N Normality of mixture =(1 × 1+1 × 2/1+1)=(3/2)=1.5 N Volume strength =(3/2) × 5.6=(16.8/2)=8.4 vol

Q. The normality and volume strength of a solution made by mixing $1.0 L$ each of $5.6$ volume and $11.2$ volume $H_{2} O_{2}$ solution are :

1 N , 5.6 vol

1.5 N, 5.6 vol

1.5 N , 8.4 vol

1 N , 8.4 vol

$1 N = 5.6 v o l$
$\Rightarrow$ Normalities of two solutions are $1 N$ and $2 N$
Normality of mixture $= \frac{1 \times 1 + 1 \times 2}{1 + 1} = \frac{3}{2} = 1.5 N$
Volume strength $= \frac{3}{2} \times 5.6 = \frac{16.8}{2} = 8.4 v o l$
