46. During the continuous discharging phase of a commercial Lead Storage Battery, what happens to th — Electrochemistry Chemistry Question

💡 Solution & Explanation

The net discharge reaction is $Pb + PbO_2 + 2H_2SO_4 \rightarrow 2PbSO_4 + 2H_2O$. Since $H_2SO_4$ is consumed to form water and solid $PbSO_4$, the concentration, specific gravity, and density of the acid electrolyte strictly decrease.
