When the same amount of zinc is treated ...

When the same amount of zinc is treated separately with excess of `H_(2)SO_(4)` and excess of NaOH, the ratio of volumes of `H_(2)` evolved is

A

`1 : 1`

B

`1 : 2`

C

`2 : 1`

D

`9 : 4`

Text Solution

Verified by Experts

The correct Answer is:
A
In both cases, the same volume of hydrogen is evolved for the same amount of zinc reacted.
`Zn + H_(2)SO_(4) rarr ZnSO_(4) + uarr`
`Zn + NaOH rarr Na_(2) ZnO_(2) + H_(2) uarr`
