Question

Justify that the reaction:
2Na(s) + H2 (g) -- 2NaH (s) is a redox reaction?????????​

Answer 1

Explanation:

2Na(s) + H2(g) → 2NaH(s)

... In the above reaction, the compound formed is an ionic compound, which may also be represented as Na+ H– (s).

....This suggests that one half reaction in this process is: 2Na(s) → 2Na+ (g) + 2e– (Oxidation) and the other half reaction is: H2(g) + 2e– → 2H– (g) (Reduction)

....So, it is evident that sodium is oxidised and hydrogen is reduced in this reaction. So, the complete reaction is a redox reaction

Answer 2

Answer:

yes ,it is a redox reaction
