Question:medium
Given below are two statements:
Statement I:
Griess–Ilosvay test is used for the detection of nitrite ion, which involves the use of sulphanilic acid and
\(\alpha\)-naphthylamine reagent.
Statement II:
In the above test, sulphanilic acid is diazotized by the acidified nitrite ion, which on further coupling with
\(\alpha\)-naphthylamine forms an azo-dye.
In the light of the above statements, choose the correct answer from the options given below.

In the light of the above statements, choose the correct answer from the options given below.
Show Hint
Most nitrite detection tests involve diazotization reactions followed by azo-coupling, producing intensely colored dyes.
