This paper describes the basic functions and features of chemical equilibrium diagram software HYDRA/MEDUSA. The application to four types of chemical equilibria, including the precipitation equilibrium, the acid-base equilibrium, the coordination equilibrium and the redox equilibrium, is illustrated. It shows that HYDRA/MEDUSA software is helpful in learning the complicated equilibrium calculations and understanding the governing factors for chemical reactions. This software can also be used for researches involving chemical equilibrium calculations as well as species distribution calculations.

Key words: Chemical equilibrium, Species distribution, HYDRA/MEDUSA software
