What does pH measure? - Studybuff

WebpH is a measure of hydrogen ion concentration. The pH scale was originated by Sorensen. He set 0 pH as the hydrogen ion concentration of a 1.0 molar solution of a strong monoprotic acid (like HCl). 14 on the pH scale uses its standard as the hydrogen ion concentration in a 1.0 molar concentration of a strong base (like NaOH).

WebRelation to pH. The molar concentration of hydronium or H + ions determines a solution's pH according to = ⁡ ([+] /) where M = mol/L. The concentration of hydroxide ions analogously determines a solution's pOH.The molecules in pure water auto-dissociate into aqueous protons and hydroxide ions in the following equilibrium: . H 2 O ⇌ OH − (aq) + … pH is defined as the decimal logarithm of the reciprocal of the hydrogen ion activity, aH+, in a solution. For example, for a solution with a hydrogen ion activity of 5×10 (at that level, this is essentially the number of moles of hydrogen ions per litre of solution) the argument of the logarithm is 1/(5×10 ) = 2×10 ; thus such a solution has a pH …
