Daniell Cell
Electrochemistry & Redox
V
The classic galvanic cell consisting of a zinc electrode in zinc sulfate and a copper electrode in copper sulfate.
Zn + Cu²⁺ → Zn²⁺ + Cu, E° = 1.10 V
Decomposition Potential
Electrochemistry & Redox
V
The minimum voltage that must be applied to an electrolytic cell before continuous electrolysis begins.
Dry Cell
Electrochemistry & Redox
V
A primary cell using a moist paste rather than a liquid electrolyte, so it can be used in any orientation.
Zn + 2MnO₂ + 2NH₄⁺ → Zn²⁺ + Mn₂O₃ + 2NH₃ + H₂O
