Explanation:
The substance that added with oxygen is said to be oxidized whereas removal of oxygen is called as reduction and the substance is said to be reduced. ...
Hence, oxygen added so here Na oxidized and reduced.
(ii) CuO changes to Cu hence oxygen is removed from CuO. Hence, CuO is reduced and is oxidized
