General and specific test
ureaBiuret 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 colorSlide7
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.Slide8
sulphanilamide
Amphoteric propertyAcid 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.Slide9
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 Slide10
