Abstract: The reaction of hydrazine with silver or several silver complexes was studied.We found that a trace copper(Ⅱ)ion is an effective catalyst.In the presence of copper(Ⅱ) ion,the rate of reaction is accelerated,and the ratio of four-electron directional reaction of hydrazine is greatly increased.With the increase of the stability constants(β2)of several silver coordination compounds.The ratio of four-electron reaction of hydrazine is decreased.The ratio of four-electron reaction against 1gβ2 of several silver coordination compounds is linear in the absence of copper(Ⅱ)ion.In the presence of copper(Ⅱ) ion, the logarithm of the ratio of one-electron reaction of hydrazine is proportional to 1/1gβ2.
