Question

When one litre one molar sulphuric acid solution is diluted with 5 L water, the normality of the obtained solution is (A)  0.2 N  (B)  0.33 N  (C)  10 N  (D)  5 N

Tardigrade Admin · Accepted Answer

Concentration before dilution, M1=1 M =2 N Volume before dilution, V1=1 L Volume after dilution, V2=1+5=6 L From normality equation, N1 V1 =N2 V2 2 × 1 =N2 × 6 N2 =(2/6)=0.33 N

Q. When one litre one molar sulphuric acid solution is diluted with $5 L$ water, the normality of the obtained solution is

$0.2 N$

$0.33 N$

$10 N$

$5 N$

Concentration before dilution, $M_{1} = 1 M = 2 N$

Volume before dilution, $V_{1} = 1 L$

Volume after dilution, $V_{2} = 1 + 5 = 6 L$

From normality equation,

$N_{1} V_{1} = N_{2} V_{2}$

$2 \times 1 = N_{2} \times 6$

$N_{2} = \frac{2}{6} = 0.33 N$

Q. When one litre one molar sulphuric acid solution is diluted with 5L water, the normality of the obtained solution is

0.2N

0.33N
