b) 
Anilinning kaliy dixromat bilan oksidlanishi 
Shisha plastinkaga bir tomchi anilin xlord tuzi eritmasidan bir tomchi tomizilib, ustiga kaliy 
dixromatning 0,5 n li eritmasi va 2 n li sulfat kislotaning eritmasidan bir tomchidan tomiziladi. Baqt 
o’tishi bilan eritma to’q yashildan avval yashil, so’ngra qora rangga o’tadi. Anilinning oksidlanishi 
molekuladagi benzol halqasining xinoid gruppaga aylanish bilan boradi. Hosil bo’lgan bo’yoq “qora
