Chapter 21 - Electrochemistry - 21.2 Half-Cells and Cell Potentials - 21.2 Lesson Check: 14

Answer

The electrical potential of a cell results from a competition for electrons between two half-cells. That is, a half-cell undergoes reduction, and thus this half-cell tends to attracts and acquire electrons. The other half-cell, which undergoes oxidation, loses electrons that are then attracted to the reduction half-cell. The transit of electrons ultimately results in an electrical potential.
