When the same amount of zinc is treated ...

When the same amount of zinc is treated separately with excess of sulphric acid and excess of sodium hydroxide, the ratio of volume of hydrogen evolved is

A

(a)1:1

B

(b)1:2

C

(c )2:1

D

(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)+H_(2)uparrow`
`Zn+NaOH rarr Na_(2)ZnO_(2)+H_(2)uparrow`
