Vedclass · Answer

(D) redox reaction is one in which both oxidation and reduction occur simultaneously,involving a change in the oxidation states of the elements.In the reaction $Cu + 2AgNO_3 	o 2Ag + Cu(NO_3)_2$:$1$. The oxidation state of $Cu$ increases from $0$ to $+2$ (Oxidation).$2$. The oxidation state of $Ag$ decreases from $+1$ to $0$ (Reduction).Since both oxidation and reduction occur,this is a redox reaction.Options $A$,$B$,and $C$ are double displacement or combination reactions where no change in oxidation states occurs.
