Strong Acids
Part of the Acids and Bases section of Coddy's Chemistry journey. Lesson 7 of 30.
A strong acid ionizes completely: every molecule gives its proton.
HCl + H₂O → H₃O⁺ + Cl⁻
For a strong acid with one proton, [H₃O⁺] = the acid's concentration. Square brackets mean concentration: [H₃O⁺] is in mol/L.
Strong acids to know: HCl, HBr, HI, HNO₃, H₂SO₄, HClO₄.
Challenge
A cleaning solution for tiles is hydrochloric acid. What is the concentration of H₃O⁺ in it?
