Vedclass · Answer

(C) $1$. Thermal decomposition of silver nitrate: $2AgNO_3 \xrightarrow{\Delta} 2Ag + 2NO_2 + O_2$. Thus,$(W) = Ag$ and $(X) = NO_2$.$2$. Reaction of $(X)$ with water: $2NO_2 + H_2O 	o HNO_2 + HNO_3$. This confirms $(X) = NO_2$.$3$. Reaction of $(W)$ with nitric acid: $3Ag + 4HNO_3 	o 3AgNO_3 + NO + 2H_2O$. Thus,$(Y) = AgNO_3$.$4$. Reaction of $(Y)$ with excess sodium thiosulfate: $AgNO_3 + 2Na_2S_2O_3 	o Na_3[Ag(S_2O_3)_2] + NaNO_3$. Thus,$(Z) = Na_3[Ag(S_2O_3)_2]$.Comparing these with the options,option $C$ is correct.

$AgNO_3 \xrightarrow{\Delta} (W) + (X) + O_2$
$(X) + H_2O \to HNO_2 + HNO_3$
$(W) + HNO_3 \to (Y) + NO + H_2O$
$(Y) + Na_2S_2O_3 (\text{excess}) \to (Z) + NaNO_3$
Identify $(W)$ to $(Z)$.
