The emf produced by Galvanic Cell is known as:
Correct answer: B. Cell Potential
- A. Redox Potential
- B. Cell Potential
- C. Oxidation Potential
- D. None of the above
Explanation
Explanation:The emf produced by the Galvanic cell is known as cell potential, which is the difference in reduction potentials of the two half-cells. This option is not correct because redox potential is a measure of the overall tendency of a system to undergo both oxidation and reduction.This option is also incorrect because the oxidation potential is related to the strength of a reducing agent, not the end product of a galvanic cell.

About Standard Hydrogen Electrode
The standard hydrogen electrode provides the reference potential of 0.00 V for measuring electrode potentials. It consists of platinum in contact with hydrogen gas at standard pressure and hydrogen ions at standard concentration, usually at 25°C, and can operate as either the oxidation or reduction half-cell.
