What does a positive value of standard electrode potential indicate?

Options

  1. AThe species on the right is more stable than hydrogen gas.
  2. BThe species on the left is more stable than hydrogen gas.
  3. CThe species on the right is less stable than hydrogen gas.
  4. DThe species on the left is less stable than hydrogen gas.

Correct answer

A. The species on the right is more stable than hydrogen gas.

Step-by-step solution

If the standard electrode potential of an electrode is greater than zero (or positive) then its reduced form is more stable compared to hydrogen gas.
