pH of Sulfuric Acid | Online Calculator for H2SO4 Acid

When you know pH, you can calculate concentration of H 3 O + ions from pH equation. Due to pH = 1, H 3 O + concentration is 0.1 mol dm -3. Due to dibasic acid, when sulfuric acid molecule dissociate, two H 3 O + ions are given. Therefore, concentration of sulfuric acid should be a half of concentration of H 3 O +.

Ammonia is a typical weak base. Ammonia itself obviously doesn't contain hydroxide ions, but it reacts with water to produce ammonium ions and hydroxide ions. However, the reaction is reversible, and at any one time about 99% of the ammonia is still present as ammonia molecules. Only about 1% has actually produced hydroxide ions.
