Question

which acid is present on car batteries ???​

Answer 1

Answer:

sulphuric acid molecules

Because the basic reactions in the battery involve uptake and release of sulphuric acid molecules, an electrolyte of sulphuric acid is used in these batteries. It is, however, possible to use other electrolytes with the lead-lead dioxide couple.

Answer 2

Lead and lead dioxide, the active materials on the battery's plates, react with sulfuric acid in the electrolyte to form lead sulfate. The lead sulfate first forms in a finely divided, amorphous state and easily reverts to lead, lead dioxide, and sulfuric acid when the battery recharges.
