The solubility product of Cul is of the order of IC'' hence in a solution having a concentration of KI equal to ro-3 g. mol per litre the concentration of Cu' ion in presence of excess of ascorbic acid would be of the order of ro-9. [...] This almost equal increment in the value of molecular rotation lends support to the view that the immediate action of the second equivalent of alkali is to ionise the hydrogen atom of the second hydroxyl group without opening the lactone ring. [...] Table II gives the range of the fall of the concentration of the indicator solution expressed in equivalents of ascorbic acid."VITAMIN C CONTENTS OF INDIAN FOODSTUFFS 17 TABLE II. [...] 1935 12 ? o) that the addition of acetic acid inhibits the -4.)ontaneons decolouration of the dye in the presence of trichloroacetic acid "18 ROTHENHEIM MAHAMl7D AND COWLAGJ The indicator was diluted with water following the observation of McHenry and Graham (Blocher'''. [...] The microphotographs of the spectra of the dyes of the three series have been taken and the absorption maxima determined.
