With respect to the electrolysis of copper (II) sulphate solution using copper electrodes, which statement is correct?2026Assertion (A): Dilute Sulphuric acid is a stronger electrolyte than concentrated Sulphuric acid.
Reason (R): Dilute Sulphuric acid has a higher concentration of mobile ions.2026Assertion (A): In the electrolysis of acidified water, the volume of hydrogen liberated is twice the volume of oxygen formed.
Reason (R): Water has hydrogen and oxygen in the ratio of 1:2 by volume.2026In the electrolysis of molten aluminium oxide for extraction of aluminium, the following reactions take place:
Al³⁺ + 3e⁻ → Al
2O²⁻ → O₂ + 4e⁻
C + O₂ → CO₂
Al₂O₃ ⇌ 2Al³⁺ + 3O²⁻
