The correct Answer is:
To determine which of the statements about the electrochemical series of reduction potentials is not correct, let's analyze each option step by step. ### Step 1: Analyze Option A **Statement:** The standard electrode potential of hydrogen is 0.00 volts. **Analysis:** This statement is true. The standard hydrogen electrode (SHE) is defined to have a potential of 0.00 volts at standard conditions. ### Step 2: Analyze Option B **Statement:** Active non-metals have positive reduction potentials. **Analysis:** This statement is also true. Active non-metals, such as fluorine and chlorine, typically have high positive reduction potentials, indicating they are strong oxidizing agents. ### Step 3: Analyze Option C **Statement:** Active metals have negative reduction potentials. **Analysis:** This statement is true. Active metals, like lithium and sodium, have negative standard reduction potentials, indicating they are more likely to lose electrons and act as reducing agents. ### Step 4: Analyze Option D **Statement:** Metals which have positive reduction potentials are good reducing agents. **Analysis:** This statement is incorrect. Metals with positive reduction potentials are actually good oxidizing agents because they tend to gain electrons rather than lose them. Good reducing agents are typically those with negative reduction potentials, as they can easily lose electrons. ### Conclusion Based on the analysis, the statement that is not correct is: **(D) Metals which have positive reduction potentials are good reducing agents.** ---

    A : Lithium is less reactive but the strogest reducing agent in aqueous solution. R : Lithium shows positive reduction potential.

    The potential associated with each electrode is known as electrode potential. If the concentration of each species taking part in the electrode reaction is unity (if any appears in the electrode reaction, it is confined to 1 atmospheric pressure) and further the reaction is carried out at 298 K, then the potential of each electrode is said to the standard electrode potential. By convention, the standard electrode potential of hydrogen electrode is 0.0 volt. The electrode potential value for each electrode process is a measure of relative tendency of the active species in the process to remain in the oxidised/reduced form. A negative E^(@) means that the redox couple is a stronger reducing agent than the H^(+)//H_(2) couple. A positive E^(@) means that the redox couple is a weaker reducing agent than the H^(+)//H_(2) couple. The metal with greater positive value of standard reduction potential forms the oxide of greater thermal stability. Which of the following couples will have highest value of emf ?
