Answer #1

Balanced "molecular" equation:
2NaCl(l) 2Na(l) + Cl2(g)

Balanced net ionic equation:
2Na+ + 2Cl- Na(l) + Cl2(g)

Sodium is reduced.
Na+ + 1e- Na(l)
Here the oxidation number becomes +1 to Zero, means it is reduced.


Chlorine is oxidized.
2Cl- Cl2(g) + 2e-

Here the oxidation number becomes -1 to Zero, means it is oxidised.
