Question

Which one is not called a anode reaction from the following
(a) Cl⁻ → 1/2 Cl₂ + e⁻
(b) Cu → Cu⁺⁺ + 2e⁻
(c) Hg⁺ → Hg⁺⁺ + e⁻ (d) Zn²⁺ + 2e⁻ → Zn

Answer 1

Answer:

Cu gives Cu 2+ + 2 electrons(b)

Explanation:

mark me as brainliest

Answer 2

Answer:

the answer is option d

Explanation:

this is because at anode oxidation takes place and oxidation means loss of electron .In the all first three options there is loss of electrons but in the fourth option there is gain of electrons so IV reaction will not occur at anode and will occur at cathode.
