Definition of diprotic acids
Check what you remember
Read the wording for your board, then hide it and explain diprotic acids in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
A diprotic strong acid supplies two protons per molecule, so 0.0200 mol dm⁻³ H₂SO₄ gives [H⁺] = 0.0400 mol dm⁻³ and pH = 1.40.
