Identify the species undergoing oxidation and reduction.
a. `H_(2)S(g)+Cl_(2)(g)rarr2HCl(g)+S(s)`
b. `3Fe_(3)O_(4)(s)+8Al(s)rarr9Fe(s)+4Al_(2)O_(3)(s)`
c. `2Na(s)+H_(2)(g)rarr2NaH(s)`

Text Solution

Verified by Experts

(i) here `H_(2)S` is oxidised to S because hydorgen has been removed form it whil `CI_(2)` has been reduced to (ii) here aluminium is oxidised to aluminium oxid because oxygen has been added to it while ferrous ferric oxide (or magnetic oxide) has been reduced to iron because oxygen has been removed from it (ii) as shown in sodium is oxidised to sodium io while hydrogen is reduced to hydride ion
