which is oxidized

Question

In the reaction 2H₂O(1)+2CI^-(aq)→H₂(g)+CI₂(g)+2OH^-(aq), which substance is oxidized, which substance is reduced, and how many electrons are transferred?

Answer 1

On the left side of the equation, H has an oxidation number of 1+ and on the right it is zero (in H2). It has been reduced.

On the left side, Cl has an oxidation number of -1 and on the right it is zero. It has been oxidized.

Two electrons have been transferred.
