6. 1. Azo dye formation test:
General test :
1. Azo dye formation test:
1 drop aniline (red color) + dil.HCl (until dissolve) + NaNO2 (sod. Nitrite solution)
until faint pale yellow color
{Diazonium salt formed}
(1)
It is unstable because that we must put it in ice, without ice it will decompose
few phenol + 10% NaOH (until phenol dissolved)
(2)
Add (1) on (2) gradually
Orange – red ppt or color
