Which of the following is laboratory preparation of dihydrogen?

$3Fe + 4H_{2}O(steam) \rightarrow Fe_{3}O_{4} + 4H_{2}$

$2Na + 2H_{2}O \rightarrow 2NaOH + H_{2}$

$CaH_{2} + 2H_{2}O \rightarrow Ca(OH)_{2} + 2H_{2}$

$Zn + H_{2}SO_{4}(dil.) \rightarrow ZnSO_{4} + H_{2}$

Answer

$Zn + H_{2}SO_{4}(dil.) \rightarrow ZnSO_{4} + H_{2}$

Explanation

: In laboratory, hydrogen gas is prepared by action of dilute $H_{2}SO_{4}$ on granulated zinc.

$Zn + H_{2}SO_{4}(dil.) \rightarrow ZnSO_{4} + H_{2}$
