Question

2NaCl + 2H,
02NaOH
H2​

Answer 1

Answer:

Na + 2H2O → 2NaOH + H2

Here oxygen is losing hydrogens so is being oxidized, The Na has gained oxygen so is reduced, Therefore, it is a redox reaction as well as H2 displacement reaction. Redox reactions are reactions in which one species is reduced and another is oxidized. Therefore the oxidation state of the species involved must change.

Answer 2

Answer:

This is an oxidation-reduction (redox) reaction:

2 HI + 2 e- → 2 H0 (reduction)

2 Cl-I - 2 e- → 2 Cl0 (oxidation)

H2O is an oxidizing agent, NaCl is a reducing agent.
