Question

AlCl3 + Na NaCl + Al Did Na change oxidation number?

Answer 1

Step-by-step explanation:

The given reaction equation is as follows.

`AlCl_(3) + Na \rightarrow NaCl + Al`

To balance this equation, we multiply Na by 3 on reactant side and NaCl by 3 also.

Thus, the balanced equation is as follows.

`AlCl_(3) + 3Na \rightarrow 3NaCl + Al`

The oxidation and reduction reaction will be as follows.

Oxidation:
`3Na \rightarrow 3Na^(+) + 3e^(-)`

Reduction:
`Al^(3+) + 3e^(-) \rightarrow Al`

Thus, we can conclude that oxidation state of sodium changes from 0 to +1.
