Question

What quantity of ammonium sulphate is necessary for the production of ammonia gas sufficient to neutralize a solution containing $292g$ of $HCl$?

[$HCl=36.5,(N{H}_4{)}_{2}S{O}_4=132,N{H}_3=17$]

• A. $272g$
• B. $408g$
• C. $528g$
• D. $1056g$

Answer 1

Answer: (C)

$528g$

Eq. of $(N{H}_4{)}_{2}S{O}_4=$Eq. of $HCl$.

Let, the amount of $(N{H}_4{)}_{2}S{O}_4$ needed is $x$ g.

Then, $\frac{x}{132/2}=\frac{292}{36.5}$.

Hence, $x=528$ g.
