6. General and specific test urea Biuret reaction: In dry test tube put few granules of urea then heat on flame until melt and solidify to give white residue. After that cool test tube + 10% NaOH drop by drop to dissolve it and give clear solution then add+ cupper sulphate → purple color

7. Urea oxalate formation: Saturated solution of urea + 1ml oxalic acid → urea oxalate as white crystalline ppt. (shiny). Urea nitrate formation: Saturated solution of urea + Conc. Nitric acid → urea nitrate as white ppt.

8. sulphanilamide Amphoteric property Acid and base test. Azo dye test: 1-Sulph. + dil Hcl to dissolve it +NaNO2 → Put in ice 2-phenol +10 % NaOH → put in ice After 5 minutes pour 1 on 2 → red orange dye.

9. phthalimide Phthaline test: Phth. + phenol + Conc. H2SO4 heat until fusions after cooling pour it in beaker contain 10 ml of 10% NaOH → unstable pink color. Fluorescence test: Phth. + resercinol +Conc. H2SO4 heat until fusion then cooling and pour it in beaker contain 10 ml 10% NaOH → reddish brown color give green fluorescence
