Options

A. Faraday
B. Coulomb
C. Cell potential
D. Ampere

Explanation

To solve the question "Cathodic standard reduction potential minus anodic standard reduction potential is equal to," we can follow these steps:

### Step 1: Define the Terms
- **Cathodic Standard Reduction Potential (E°_cathode)**: This is the potential associated with the reduction reaction occurring at the cathode.
- **Anodic Standard Reduction Potential (E°_anode)**: This is the potential associated with the reduction reaction occurring at the anode.

### Step 2: Write the Expression
The question asks for the difference between the cathodic and anodic standard reduction potentials. We can express this mathematically as:
\[ E°_{cell} = E°_{cathode} - E°_{anode} \]

### Step 3: Understand the Cell Potential
The cell potential (E°_cell) is the driving force for the electrochemical reaction. It indicates how much energy is available to do work when the cell operates. The higher the cell potential, the more spontaneous the reaction.

### Step 4: Conclusion
Thus, we conclude that:
\[ E°_{cell} = E°_{cathode} - E°_{anode} \]

### Final Answer
The difference between the cathodic standard reduction potential and the anodic standard reduction potential is equal to the cell potential (E°_cell).
