Sulfuric acid (H2So4) has a pH of 0.5 at a concentration of 33.5%, which is equivalent to the concentration of sulfuric acid used in lead-acid batteries. Sulfuric acid is one of the most important industrial chemicals. Why is sulfuric acid used instead of hydrochloric acid? Sulfuric acid is used almost universally for neutralization reactions.Web
