(D) The reagent consisting of $1$-naphthylamine and sulphanilic acid in acetic acid is known as the Griess reagent.It is specifically used for the detection of nitrite ions $(NO_{2}^{-})$.The test involves the diazotization of sulphanilic acid by nitrous acid $(HNO_{2})$,which is formed from $NO_{2}^{-}$ in the presence of acetic acid.The resulting diazonium salt then couples with $1$-naphthylamine to form a red-colored azo dye,indicating the presence of $NO_{2}^{-}$.
