# NCERT

8.17  Consider the reactions:

(c)C_{6}H_{5}CHO(l)+2[Ag(NH_{3})_{2}]^{+}(aq)+3OH^{-}(aq)\rightarrow C_{6}H_{5}COO^{-}(aq)+2Ag^{+}(s)+4NH_{3}(aq)+2H_{2}O(l)

(d)C_{6}H_{5}CHO(l)+2Cu^{2+}(aq)+5OH^{-}(aq)\rightarrow No change observed

Answer-

Here, by looking at the reaction, we conclude that  Ag^{+} oxidises C_{6}H_{5}CHO and in the second reaction Cu^{+} not able to oxidise. So we can say that Ag^{+}is stronger oxidizing agent than Cu^{+}.
