Chemistry - Electrochemistry Question with Solution | TestHub

In Daniell cell, during the passage of electric current through external circuit, electrons flow from the zinc electrode to the copper electrode. At the zinc electrode, the zinc metal is oxidised to ${\mathrm{Zn}}^{++}$which go into the solution. The electrons released at the electrode travel through the external circuit to the copper electrode where they are used in the reduction of ${\mathrm{Cu}}^{2+}$ ions to metallic copper which is deposited on the electrode.
