The acid generally stored in batteries is
Answer: C
Batteries hold sulphuric acid.
A lead-acid cell uses about 35 per cent \(\mathrm{H_2SO_4}\) as electrolyte: \[\mathrm{Pb + PbO_2 + 2H_2SO_4 \rightarrow 2PbSO_4 + 2H_2O}\] The acid is consumed on discharge, so the electrolyte's specific gravity falls - which is how a hydrometer reads a battery's state of charge.
