When the same amount of zinc is treated ...

When the same amount of zinc is treated with excess if `H_2SO_4` and with excess if NaOH, the ratio of the volumes of `H_2` evolved , is

A

3:2

B

1:2

C

`2:1`

D

`1:1`

Text Solution

Verified by Experts

The correct Answer is:
(d)
`Zn+H_2SO_4 to ZnSO_4+H_2`
(1Mole)
`Zn_2+NaOH to Na_2ZnO_2+H_2`
(1Mole)
therefore In both the reactions , 1 mole if `H_2` is evolved , hence the ratio of volumes 1:1 .
