Where Is Sulfuric Acid on the PH Scale?
Sulfuric acid has a pH of 0.3 at a normality of 1 N, a pH of 1.2 at 0.1 N and a pH of 2.1 at 0.01 N. When using molar concentration, sulfuric acid has a pH of 2.75 at 1 millimole per liter, a pH of 1.87 at 10 millimoles per liter and a pH of 1.01 at 100 millimoles per liter.
Sulfuric acid, or H2SO4, is highly corrosive and causes very serious damage at high concentrations. It is an ingredient in fertilizer, household drain cleaners, cleaning products, pharmaceuticals and dyes. Acid rain contains diluted sulfuric acid, but pure sulfuric acid does not naturally occur on Earth in its anhydrous form.
