Abstract
Vitamin C in aqueous solution shows concentration v s absorbance a linear relationship for dilute solutions (0.004 % to 0.005 % w/v). The pH also affects the linearity of the curve such as pH 3 is found to give a linear relationship between concentration and absorbance up to a wide range (0.001 % to 0.009 % w/v). The E (I %, 1 cm) values at pH 3 may be exploited to determine the % age purity of the vitamin C in separate vitamin C tablets or syrups. This method for the quantitatiye determination of vitamin C is more accurate, precise and applicable as compared to simple methods of UV spectrophotometry.
