0.7 g of ${({NH}_{4})}_{2} {SO}_{4}$ sample was boiled with 100 mL of 0.2 N NaOH solution till all the ${NH}_{3}$ gas is evolved. The resulting solution was diluted to 250 mL. 25 mL of this solution was neutralized using 10mL of a 0.1 N $H_{2} {SO}_{4}$ solution. The percentage purity of the ${({NH}_{4})}_{2} {SO}_{4}$ sample is:

Detailed Solution

Milli equivalent of $H_{2} {SO}_{4} = 10 \times 0.1 = 1 in 25 mL$

$∴$ $meq. in 250 mL = 10$

Milli equivalent of NaOH taken = 100 x 0.2 = 20

Milli equivalent of NaOH used

$= 10 meq \cdot of {({NH}_{4})}_{2} {SO}_{4}$

$\begin{array}{l} \frac{W}{\frac{W 2}{2}} \times 1000 = 10 \\ % purity = \frac{0.66}{0.7} \times 100 \end{array}$

% purity = 94.3
