Answered: The concentration of sulfuric acid in… | bartleby
The concentration of sulfuric acid in the lead storage battery of an automobile over a period of time has decreased from 38.0 percent by mass (density = 1.29 g mL-) to 26.0 percent by mass (1.19 g mL ). Assume the volume of the acid remains constant at 724 mL. (a) Calculate the total charge in coulombs supplied by the battery.
Contact UsShould I Add Acid Or Water To The Battery?
As stated earlier, under normal circumstances, the battery will never lose sulfuric acid but will only lose water. That means the levels of sulfuric acid either free or in the plates remain the same. When you add more acid to the battery, it means the level of sulfuric acid concentration will increase dramatically with every drop added.
