Chemistry - Electrochemistry Question with Solution | TestHub

Aqueous solution of LiCl contains Li⁺, H⁺, Cl⁻, and OH⁻ ions. H⁺ would be preferentially reduced at the cathode, while at the anode, OH⁻ ions would be oxidized. Thus, H₂ and O₂ gases are liberated at the cathode and anode, respectively. As the current flows, H⁺ ions around the cathode get discharged to give H₂ gas, so the pH of the solution around the cathode increases.
