Some of the following gases are soluble in water due to formation of their ions :
`I:CO_(2), II:NH_(3), III:HCL, IV:CH_(4), V:H_(2)`
Water insoluble gases can be:

Options

A. I,IV,V
B. I,V
C. I,II,III
D. IV,V

Answer

D

Explanation

`CO_(2)+H_(2)OrarrH_(2)CO_(3)rarr2H^(+)+CO_(3)^(-2)`
`NH_(3)+H_(2)OrarrNH_(4)OHrarrNH_(4)^(+)+OH^(-)`
`HCl+H_(2)OrarrH_(3)O^(+)+Cl^(-)`
But `CH_(4)` and `H_(2)` are insoluble gases in water.
