The chemical reaction for laboratory preparation of water is shown below-Zn-H2SO4-x27F6-ZnSO4-H2-orZn-HCl-x27F6-ZnCl2-H2This shows that in either case-H- is being reduced to H2-

In the laboratory preparation of dihydrogen, which of the following species is reduced?Zn+H+Both A and BNone of the above

The chemical reaction for laboratory preparation of water is shown below:Zn+H2SO4⟶ZnSO4+H2,orZn+HCl⟶ZnCl2+H2This shows that in either case,H+ is being reduced to H2.

In the laboratory preparation of dihydrogen, which of the following species is reduced?
$Z n^{+}$
$H^{+}$
Both $A$ and $B$
None of the above

The chemical reaction for laboratory preparation of water is shown below:
$Z n + H_{2} S O_{4} ⟶ Z n S O_{4} + H_{2}$ ,or
$Z n + H C l ⟶ Z n C l_{2} + H_{2}$
This shows that in either case, $H^{+}$ is being reduced to $H_{2}$ .
