Electrochemistry is the study of reactions in which charged particles (ions or electrons) cross the interface between two phases of matter, typically a metallic phase (the electrode) and a conductive solution, or electrolyte.

Reactions in galvanic cells are

The pure metal at higher energy will always have a tendency to go into the higher energy state by the attack of environment.

In which direction does electricity flow in a galvanic cell (battery)?

What is the standard electrode potential for H₂(g)?
