Some Basic Concepts Of Chemistry Question 217
Question: What quantity of ammonium sulphate is necessary for the production of $ NH _3 $ gas sufficient to neutralize a solution containing 292 g of $ HCl $ ? [HCl=36.5; $ {{(NH _4)}_2}SO _4 $ =132; $ NH _3 $ =17] [CPMT 1992]
Options:
A) 272 g
B) 403 g
C) 528 g
D) 1056 g
Show Answer
Answer:
Correct Answer: C
Solution:
$ \underset{132}{\mathop{{{(NH _4)}_2}SO _4}},\equiv 2NH _3\equiv \underset{2(36.5)=73,gm}{\mathop{2HCl}}, $
$ 73,g,HCl\equiv 132,g{{(NH _4)}_2}SO _4 $
$ 292,g,HCl=528,g{{(NH _4)}_2}SO _4 $
