QQuestion

Which of the following reactions takes place at the anode during the electroplating of an article with silver? [1]

  1. Ag − 1e ⟶ Ag1+
  2. Ag + 1e ⟶ Ag1−
  3. Ag − 1e ⟶ Ag
  4. None of the above

Exam-ready answer 01 Mark

Answer

a. Ag − 1e ⟶ Ag1+

Explanation:

  1. During electroplating, the silver anode loses electrons.
  2. Silver atoms form Ag1+ ions in the solution.

Anode reaction:

Ag − 1e ⟶ Ag1+
