Determination of hydrazine by gas evolution.

A method is proposed for the determination of mg amounts of hydrazine based on the measurement of the volume of nitrogen evolved after oxidation with silver(I) oxide.

Reduction of silver(II) oxide by the solvent in acid media.

The reaction of silver(II) oxide with water to yield silver(I) ions and oxygen is an important side-reaction in procedures which use silver(II) oxide as the oxidant. This reaction has been examined in solutions which were 0.01-1M in respect to sulphuric or perchloric acid. The rate of reduction varied directly with the amount of solid added and was a complex function of the concentrations of hydrogen ions, silver(I) ions and anions present. The kinetic results have been used to postulate a mechanism for the reaction.
