Question

Explain the redox potential.

Hint:

A higher redox potential means a species is more readily reduced. Conversely, a lower redox potential indicates it is more likely to be oxidized.

Answer 1

Step 1: Define Redox Potential
Redox potential, also known as electrode potential, refers to the tendency of a chemical species to acquire electrons and thereby be reduced. It is measured in volts (V). The standard redox potential is denoted as \(E^\circ\), which is the potential of a half-cell in standard conditions (1 M concentration, 1 atm pressure, 25°C).
Step 2: Relation to Electrode Reactions
The redox potential indicates how easily a species gains or loses electrons. A positive \(E^\circ\) value indicates that the species is more likely to be reduced (gain electrons), while a negative \(E^\circ\) value suggests that it is more likely to be oxidized (lose electrons). Final Answer: Redox potential quantifies the ability of a species to either gain or lose electrons during redox reactions. Correct Answer: Redox potential refers to the tendency of a species to gain or lose electrons.
