Question

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 )

Answer 1

oxidized substance is Cu

Reduced substance is Ag

Oxidizing agent is Ag

reducing agent is Cu

Step-by-step 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.
