Question

Select the incorrect statement

• A. Fluorine gas is the strongest oxidising agent
• B. Lithium ion is weakest oxidising agent
• C. If the standard reduction potential is positive then hydrogen gas is more stable than reduced form
• D. Lithium metal is powerful reducing agent in an aqueous solution

Answer 1

Answer: (C)

If standard electrode potential is negative then hydrogen gas is more stable than reduced form of the species.
The standard electrode potential for fluorine is highest which indicates that fluorine gas $\left(F_2\right)$ has maximum tendency to get reduced to fluoride ions $\left(F^{-}\right)$and fluorine gas is the
strongest oxidising agent but fluoride ion is the weakest reducing agent.
Lithium has lowest electrode potential indicating that Li ion is weakest oxidising agent while Li metal is the most powerful reducing agent.
