Abstract: Alkalimetric titration of hydrazine hydrate (I) results in values too high because NH3 forms in the decompn. of I. It is recommended that NH3 be detd. from the difference of alkalimetric and oximetric titrations. These results agree with detns. of NH3 in I by distn. HCl (0.5N) is best for the alkalimetric titration. For oximetric titration, 0.1N KMnO4 in dil. H2SO4 with KBr is preferable after completing the alkalimetric detn.
