Identify the oxidized substance, the reduced substance, the oxidizing agent, and the reducing agent in the redox reaction. Cu (s) + 2 AgNO 3 (aq) ⟶ 2 Ag (s) + Cu (NO 3) 2 (aq)

oxidized substance is Cu

Reduced substance is Ag

Oxidizing agent is Ag

reducing agent is Cu

Explanation:

oxidation is an increase in the oxidation number of an element, reduction however is the opposite.

The oxidation number of a neutral or free element is 0.

From the equation Cu is oxidized to Cu (NO 3) 2, as the oxidation number of copper increased from 0 in Cu to + 2 in Cu (NO 3) 2.

Ag is reduced as the oxidation state is decreased from + 1 in AgNO3 to 0 in Ag

Hence the oxidizing agent is silver and reducing agent is Cu.

oxidized substance is Cu and reduced substance is Ag.
