Vedclass · Answer

(C) Aqueous solution of silver nitrate $(X = AgNO_3)$ reacts with $NH_4OH$ to form a brown precipitate of silver oxide $(Y = Ag_2O)$. $2AgNO_3 + 2NH_4OH \longrightarrow Ag_2O + 2NH_4NO_3 + H_2O$ This precipitate dissolves in excess $NH_4OH$ to form the diamminesilver$(I)$ complex,$[Ag(NH_3)_2]^+$,which is known as Tollen's reagent. $Ag_2O + 4NH_3 + H_2O \longrightarrow 2[Ag(NH_3)_2]^+ + 2OH^-$ Tollen's reagent is reduced by acetaldehyde $(CH_3CHO)$ to deposit metallic silver $(Ag)$. $CH_3CHO + 2[Ag(NH_3)_2]^+ + 3OH^- \longrightarrow CH_3COO^- + 2Ag + 4NH_3 + 2H_2O$

Aqueous solution of a metallic nitrate $X$ reacts with $NH_4OH$ to form $Y$,which dissolves in excess $NH_4OH$. The resulting complex is reduced by acetaldehyde to deposit the metal. $X$ and $Y$,respectively,are
