Where does the oxidation takes place in Daniel cell?

In Daniel cell, oxidation takes place at the anode.

Daniel cell

A Daniell cell is a galvanic cell that converts chemical energy into electrical energy. The cell comprises a copper vessel filled with saturated CuSO₄ solution, i.e. depolarizer, and dilutes H₂SO₄ is filled which acts as an electrolyte. An amalgamated zinc rod is immersed in H₂SO₄. This rod acts as a negative electrode or cathode. In copper vessels, there is a transparent layer all around just below the upper surface in which CuSO₄ crystals are kept in contact with CuSO₄ solution. Due to this, the solution always remains saturated.

• The Daniell cell can be conventionally represented as

Zn(s) + Cu²⁺(aq) → Zn²⁺(aq) + Cu(s)

Ion Zn/ZnSO₄ half cell, an oxidation reaction occurs.

Zn → Zn²⁺ + 2e^–

Ion Cu/CuSO4 half cell, a reduction reaction occurs.

Cu²⁺ + 2e^– → Cu

The net cell reaction is

Zn + Cu²⁺ ⇌ Zn²⁺ + Cu
