Vedclass · Answer

(D) In the manufacture of mirrors,ammoniacal $AgNO_3$ (Tollens' reagent) and $HCHO$ (formaldehyde) are used.The process involves the reduction of silver ions to metallic silver,which deposits on the glass surface to form a reflective mirror coating.The chemical reaction is:$HCHO + 2[Ag(NH_3)_2]^+ + 3OH^- \rightarrow HCOO^- + 2Ag(s) + 4NH_3 + 2H_2O$Here,$HCHO$ acts as a reducing agent,reducing the silver complex to metallic silver $(Ag(s))$,which forms the mirror.
