Which of the following statements is strictly INCORRECT regarding the discharging process of a comme — Electrochemistry Chemistry Question

💡 Solution & Explanation

During the discharge of a lead storage battery, the overall reaction is $Pb + PbO_2 + 2H_2SO_4 \rightarrow 2PbSO_4 + 2H_2O$. Because $H_2SO_4$ is continuously consumed and water is produced, the concentration and density of the sulphuric acid electrolyte strictly decrease, not increase.
