2g of aluminium is treated separately with excess of dil. `H_(2)SO_(4)` and excess of NaOH, the ratio of volume of hydrogen evolved is :

A

`2:3`

B

`1:1`

C

`2:1`

D

`1:2`

Text Solution

Verified by Experts

The correct Answer is:
B
`2 AI + 3H_(2) SO_(4) rarr AI_(2) (SO_(4))_(3) + 3H_(2): 2AI + 2NaOH+ 2H_(2) O rarr 2Na AIO_(2)+ 3H_(2)`
Thus ratio of volumes of hydrogen evolved is 1:1
