Solve this:
Q.4. When H 2 reacts with Na, it acts as ?
(1) Oxidising agent
(2) Reducing agent
(3) Both
(4) None
 

Dear Student,

Reaction Involved:  Na + H2 NaH
In this case,

Sodium is Oxidized from Na (O.S. = 0) to Na+(O.S. = +1).
And Hydrogen is reduced from H2(O.S. = 0) to H- (O.S. = -1)

So,

Oxidizing Agent is H2.
And Reducing Agent is Na.

Therefore, option (1) is correct.

Hope this information clears your doubts about the topic.

Keep asking!!

Regards
