The oxidation number of copper in reactant half cell is 0 but the oxidation number of copper in product half cell is 2. As there is an increase in the oxidation number of copper so copper is being oxidized.


The oxidation number of Silver in reactant half cell is +1 but the oxidation number of Silver in product half cell is 0. As there is an decrease in the oxidation number of Silver so silver is being reduced.


Oxidizing agents are the substance which oxidize other substance and get reduced themselves so silver is oxidizing agent here.


Reducing agents are the substance which reduce other substance and get oxidized themselves so copper is reducing agent here.
