Abstract

The main objective of this experiment is to determine the amount of nicotine in commercial brand bidis and cigarettes by means of a nonaqueous acid-base titration. This study focus on harmful level of nicotine present in bidis and cigarettes by comparative study of titration analysis with marketed tobacco powder.Nicotine is weak base so treatment with alkali strengthens it for acid-base reaction. Due to alkaloid in nature, nicotine was extracted out by highly organic solvent like toluene or diethyl ether etc. The liberated nicotine was titrated with perchloric acid using crystal violet indicator. Result shows that Marketed Tobacco powder and local bidis had more concentration of nicotine as compare to branded cigarettes.
