Question:

The half-cell reaction is the one that.......

Options:

consumes half mole of an electrolyte

takes place at one electrode

reduces the concentration of electrolyte to half of its initial value

reduces the electrode potential to half its initial value

Correct Answer:

takes place at one electrode

Explanation:

The correct answer is Option (2) → takes place at one electrode

A half-cell reaction refers to the oxidation or reduction reaction that occurs at a single electrode in an electrochemical cell.

  • It does not necessarily involve halving concentration or electrode potential.
  • It simply represents one half of the overall redox reaction
