Strong Acids (HCl, HNO3, H2SO4) - Aqion

Approximations. If we ignore activity corrections at all, that is, if we set log γ = 0, then we get two approximate formulas: (2) pH ≈ -log [HA] (for monoprotic acid HA) (3) pH ≈ -log 2 [H 2 A] (for diprotic acid H 2 A) The factor 2 in 3 results from the fact that H 2 SO 4 can release two H + ions.
