Options

A. It can act as a reducing agent only
B. It can act as an oxidising agent only
C. It can act as both as oxidising and reducing agents
D. It can act neither as an oxidising nor as a reducing agent.

Answer

3

Explanation

Hydrogen can act both as oxidising and reducing agent. It acts as oxidising agnet when reacts with metal and form emtal hydrides which are elctrovalent compounds.
`2Na+H_(2)rarr2Na^(+)H^(c-)`
`Ca+H_(2)rarrCaH_(2)`
Hydrogen also acts as reducing agent when its reacts with oxides
`PbO+H_(2)rarrPb+H_(2)O`
`CuO+H_(2)rarrCu+H_(2)O`
`Fe_(3)O_(4)+H_(2)rarr3Fe+4H_(2)O`
