Question

The solid product formed on heating $AgN{O}_3$ strongly to $980K$ is :

• A. Silver carbonate
• B. Silver nitride
• C. Silver oxide
• D. Silver metal

Answer 1

The correct option is D Silver metal

$AgN{O}_3$ when heated above ${212}^{o}C$, decomposed to give silver nitrite and oxygen but when heated at high temperature (i.e., 380 K), it gives silver metal.

$2AgN{O}_3\underset{△}{\overset{>{212}^{o}C}{\to }}AgN{O}_2+O_2\stackrel{980K;△}{\to }2Ag\downarrow +2N{O}_2+O_2$

Hence, option $D$ is correct.
