Question

Observe the picture and complete the table.

Anode
Cathode
Electrolyte
Equation of the chemical reaction taking place at the anode
Equation of the chemical reaction taking place at the cathode

Accepted Answer

a) Anode: Impure copper. Impure copper metal is used as an anode.

b) Cathode: Pure copper: Pure thin copper metal is used as a cathode.

c) Electrolyte: Copper sulphate solution with sulphuric acid: Acidified(sulphuric acid) copper sulphate solution is used as an electrolyte.

d) Equation of the chemical reaction taking place at the anode: $C u \overset{}{\to} C u^{2 +} + 2^{e -}$ . Copper metal is oxidised to $C u^{2 +}$ by losing two electrons

Anode Impure copper

Cathode Pure copper

Electrolyte Copper sulphate solution with acidified sulphuric acid

Equation of the chemical reaction taking place at the anode $C u \underset{}{\to} C u^{2 +} + 2^{e -}$

Equation of the chemical reaction taking place at the anode $C u^{2 +} + 2^{e -} \underset{}{\to} C u$

e) Equation for the chemical reaction taking place at the cathode: $C u^{2 +} + 2^{e -} \underset{}{\to} C u$ . $C u^{2 +}$ gains two electrons and reduced to copper metal.
