Answer:
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.
