Question

Dihydrogen is prepared by the reaction of Zn with (a q) NaOH. Which of the following compounds is produced with dihydrogen during the course of reaction? (A) Zinc oxide (B) Zinc hydroxide (C) Sodium zincate (D) None of these

Tardigrade Admin · Accepted Answer

The reaction between Zn and NaOH is shown below: Zn +2 NaOH (a q) longrightarrow underset textSodium zincateNa 2 ZnO 2+ underset textDihydrogen H 2 uparrow Thus, sodium zincate is produced in the reaction.

Q. Dihydrogen is prepared by the reaction of $Z n$ with $(a q) N a O H$ . Which of the following compounds is produced with dihydrogen during the course of reaction?

Zinc oxide

Zinc hydroxide

Sodium zincate

None of these

The reaction between $Z n$ and $N a O H$ is shown below :
$Z n + 2 N a O H (a q) ⟶ Sodium zincate N a_{2} Z n O_{2} + Dihydrogen H_{2} ↑$
Thus, sodium zincate is produced in the reaction.
