MCQ
Which statement is true for solution of $0.020\,M $ ${H_2}S{O_4}$
  • A
    $2\,litre$ of the solution contains $0.020\,mole$ of $SO_4^{2 - }$
  • $2\,litre$ of the solution contains $ 0.080\,mole$ of ${H_3}{O^ + }$
  • C
    $1\,litre$ of the solution contains $0.020\,mole$ ${H_3}{O^ + }$
  • D
    None of these

Answer

Correct option: B.
$2\,litre$ of the solution contains $ 0.080\,mole$ of ${H_3}{O^ + }$
b
(b)$[{H_3}{O^ + }] = 2 \times 0.02 = 0.04\,M$

$ 2\,litre$ solution contains $0.08\,mole$ of ${H_3}{O^ + }$.
