Experiment one particular


To detect arsenic intoxication adulterants in fat, petrol and chausser.


Test-tube, acetic anhydride, conc. H2SO4, acetic acid, conc. HNO3.


Common adulterants present in ghee and essential oil are paraffin wax, hydrocarbons, dyes and argemone essential oil. These are discovered as follows: (i)В В Adulteration of paraffin wax and hydrocarbon in vegetable ghee- Heat small amount of vegetable ghee with acetic anhydride. Droplets of oil floating around the surface of unused acetic anhydride implies the presence of feel or hydrocarbons.

(ii)В Adulteration of dyes in fat-

High temperature 1mL of fat with a mixture of 1mL of conc. sulphuric chemical p and 4mL of acetic acid. Appearance of pink or perhaps red coloring indicates occurrence of coloring in excess fat.

(iii)В В Adulteration of argemone olive oil in edible oils-

To small amount of oil in a test-tube, add few drops of conc. HNO3В and shake. Overall look of reddish colour inside the acid coating indicates occurrence of argemone oil.
