Galvanic Cell (Daniell)
Medium+80 XP
In a Daniell cell, zinc dissolves and copper plates out — electrons travel through the wire and ions through the salt bridge. Watch the whole circuit in 3D.
›EMF = E°cathode − E°anode; for spontaneous reaction EMF > 0.
›Nernst equation: E = E° − (0.0591/n) × log Q (at 298 K).
