Find the incorrect statement

Options

A. Higher reduction potential of non-metal means stronger reducing agent
B. Lower oxidation potential of a metal means strong oxidising agent
C. Oxidation state of oxygen in `O_(3)` is -1
D. All of these

Answer

To find the incorrect statement regarding redox reactions and standard reduction potentials (SRP), we can analyze the information provided in the video transcript step by step.

### Step-by-Step Solution:

1. **Understanding Standard Reduction Potential (SRP):**
- The standard reduction potential (SRP) is a measure of the tendency of a chemical species to be reduced. A higher SRP indicates a stronger oxidizing agent, while a lower SRP indicates a stronger reducing agent.

2. **Electrochemical Series:**
- The electrochemical series ranks elements based on their SRP values. Elements at the top (like lithium and potassium) have lower SRP values and are stronger reducing agents. Elements at the bottom (like fluorine) have higher SRP values and are stronger oxidizing agents.

3. **Relationship between SRP and SOP:**
- The standard oxidation potential (SOP) is related to SRP by the equation:
\[ \text{SOP} = -\text{SRP} \]
- This means that a lower SRP corresponds to a higher SOP. Therefore, a good reducing agent will have a low SRP and a high SOP.

4. **Analyzing the Statements:**
- The statement "high reduction potential means stronger reducing agent" is incorrect. A high SRP indicates a stronger oxidizing agent, not a reducing agent.
- The statement "lower SRP means better reducing agent" is correct, as discussed.

5. **Oxidation States in Elements:**
- The oxidation state of elements in their elemental form (like O3, P4) is zero. This is a fundamental concept in chemistry.

6. **Conclusion:**
- The incorrect statement is: "high reduction potential means stronger reducing agent."

### Summary of Incorrect Statement:
- The incorrect statement is: "high reduction potential means stronger reducing agent."
