“…21 The weak bases which cannot be determined visually or potentiometrically, either in acetic acid or in propionic acid, can be titrated in acetic anhydride with perchloric acid in acetic acid. 22,23 In order to estimate sulphur, it has been found that mercapto group in thioglycolic acid, thiourea and thiosemicarbazide can be oxidized in the lead tetra-acetate to various oxidation states depending on the nature of the medium. In glacial acetic acid these compounds were oxidized to disulphides.…”

Oxidimetric quantitative determination of arsenic(III) in organic arsines and their complexes with tin(IV) and mercury(II) has been attempted visually, potentiometrically and conductometrically. In each method, standard potassium bromate and potassium iodate oxidants were used in absolute alcohol medium. In these methods, known weight of organic arsines was dissolved in a mixture of absolute alcohol and concentrated hydrochloric acid. The resulting solution was titrated with standard potassium bromate/iodate solutions as oxidants using CCl 4 as indicator in visual method. In case of conductometric and potentiometric titrations using potassium iodate/bromated, the results obtained were comparable to visual method. The percentage of arsenic for 1/10 mol L -1 KIO 3 and 1/10 mol L -1 KBrO 3 were found to be 11.73% and 11.71%, respectively. It led to the authenticity of the results obtained by visual method. 10 mg to 20 mg of the compound under test gave the results within the standard deviation error. The estimation of arsenic (III) was achieved within half an hour.
