Definition of strong acid pH
Check what you remember
Read the wording for your board, then hide it and explain strong acid pH in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
For a strong monoprotic acid the dissociation is complete, so every mole of acid delivers a mole of H⁺ and [H⁺] is simply the acid concentration, with pH = −log₁₀[H⁺].
