MCQ
Which one of the following compounds on strong heating evolves ammonia gas?
  • ✓
    $(NH_4)_2SO_4$
  • B
    $HNO_3$
  • C
    $(NH_4)_2Cr_2O_7$
  • D
    $NH_3NO_3$
✓

Answer

Correct option: A.
$(NH_4)_2SO_4$
a
$\left( NH _4\right)_2 Cr _2 O _7 \rightarrow N _2$

$NH _4 NO _3 \rightarrow N _2 O$

$NH _4 NO _2 \rightarrow N _2$

$\left( NH _4\right)_2 SO _4 \rightarrow NH _3$

Ammonia is obtained by heating ammonium sulphate.

$\left( NH _4\right)_2 SO _4 \rightarrow NH _3+ NH _4 HSO _4$
