Study Notes
Electrochemical Cells
- An electrochemical cell is a type of cell that converts chemical energy to electrical energy.
Cell Terminals
- The negative (−) terminal of an electrochemical cell is called the anode.
Electrochemistry
- Electrochemistry is the branch of chemistry that deals with the interconversion of chemical energy to electrical energy and vice versa.
Daniel Cell
- The overall reaction in a Daniel cell involves the oxidation of zinc (Zn) at the anode and the reduction of copper (Cu) at the cathode.
- The flow of electrons in a Daniel cell is from the zinc anode to the copper cathode.
