Answer 2

Answer:

As the battery discharges, the sulphuric acid reacts with the lead to form lead sulphate and water. The reaction is reversed when the battery is recharged.

The state of charge of the battery can be determined by measuring the strength of the acid. The usual instrument for doing this test is a hydrometer, it measures the density of the electrolyte (the name given to the fluid in a battery). Water has a different density to sulphuric acid, so the strength of the acid can be determined by measuring the density
