Vedclass · Answer

(D) The preparation of looking mirrors (silvering of glass) is based on the Tollens' test,which involves the reduction of ammoniacal silver nitrate ($AgNO_3$ + $NH_4OH$) to metallic silver by an aldehyde. $HCHO$ (formaldehyde) is commonly used as the reducing agent to deposit a thin,uniform layer of silver on the glass surface. Therefore,the process involves the use of ammoniacal silver nitrate and $HCHO$.
