초록

산화-환원반응은 수용액에서 일어나는 여러 중요한 반응중 하나이다. 산화-환원반응의 평형을 해석하는 것은 습식제련에서 침출, 분리 및 전기화화반응과 같은 단위공정을 설계하는데 있어 큰 도움이 된다. Frost도를 작성하는 방법을 설명하고, Frost도와 Latimer 표로부터 불균등화반응과 균등화반응이 일어나는 조건을 해석하였다. 또한 Frost도로부터 얻을 수 있는 정보에 대해 고찰하였다.

Oxidation-reduction reaction is one of the most important reactions occurring in the aqueous phase. Analysis of the equilibria related to these oxidation-reduction reactions is of great value in designing many unit operations in hydrometallurgy, such as leaching, separation and electrochemical reactions. The construction of Frost diagram was discussed in this work. The conditions at which disproportionation and proportionation reactions can occur were explained by analyzing Frost diagram together with Latimer table. The information which can be obtained from Frost diagram was discussed.
