Abstract

The anodic oxidations of the Silver(I) / Silver(II) / Silver(III) system have been studied in aq. 2M $AgNO_3$ solution with Platinum and Carbon electrodes. It has been found that $Ag_7O_8NO_3$ can be produced at relatively higher current density. Deposited black Oxy-salt were analyzed with several methods such as oxidizing power, X-ray powder diffraction patterns, thermal analysis, and reduction curves. It decomposed to AgO upon being suspended in boiling water. AgO compound obtained from $Ag_7O_8NO_3$ were purer and denser than Alfa-product AgO.

2M $AgNO_3$ 수용액을 백금이나 탄소 전극을 이용하여 비교적 높은 전류밀도에서 전해 산화하였다. 이 생성물을 산화력과 X-ray powder diffraction patterns, thermal analysis, 그리고 환원 곡선등을 구하여 $Ag_7O_8NO_3$ 임을 확인하고 끓는물에서 가수분해 하여 Alfa-product AgO보다 순도가 높고 비중이 큰 AgO를 얻을 수 있었다.
