MCQ
How many litres of $C{O_2}$ at $STP $ will be formed when $100\,ml$ of $0.1\,M\,{H_2}S{O_4}$ reacts with excess of $N{a_2}S{O_3}$
  • A
    $22.4$
  • B
    $2.24$
  • ✓
    $0.22$
  • D
    $5.6$
✓

Answer

Correct option: C.
$0.22$
c
(c)$\mathop {N{a_2}C{O_3}}\limits_{} \,\, + \mathop {{H_2}S{O_4}}\limits_{98\,gm\,(2mole)} \to \mathop {N{a_2}S{O_4}}\limits_{1\,mole} + \mathop {C{O_2}HO}\limits_{1\,mole} $

$0.02 = \frac{{0.02 \times 22.4}}{2} = 0.224$.
