Question

The standard oxidation potential of $A,B,C,D$ are $-0.55,0.86,-0.21$ and $+0.38$ volts respectively. Identify the strongest reducing agent.

• A. $A$
• B. $B$
• C. $C$
• D. $D$

Answer 1

Answer: (B)

$B$

The standard oxidation potential is the tendency for a chemical species to be oxidized or act as a reducing agent and is measured in volts at standard conditions.

The more positive the potential is the more likely it will be reduced. Here, $B$ has the highest potential $+0.86$ volts.

Thus, $B$ is the strongest reducing agent.
