Web2 mei 2024 · How to Calculate pH and [H+] The equilibrium equation yields the following formula for pH: pH = -log 10 [H +] [H +] = 10 -pH. In other words, pH is the negative log of the molar hydrogen ion concentration or the molar hydrogen ion concentration equals 10 to the power of the negative pH value. It's easy to do this calculation on any scientific ... Web30 jul. 2024 · Learning Objectives. The pH of a solution is a measure of the concentration of hydrogen ions in the solution. A solution with a high number of hydrogen ions is acidic and has a low pH value. A solution with a high number of hydroxide ions is basic and has a high pH value. The pH scale ranges from 0 to 14, with a pH of 7 being neutral.

In water of in een waterige oplossing is een klein deel van de watermoleculen aanwezig in de vorm van ionen (autoprotolyse). Twee H2O-moleculen vormen dan een positief H3O -ion en een negatief OH -ion. Het oplosbaarheidsproduct van de beide ionen in water is 10 mol/l (bij 22 °C), dat wil zeggen dat voor elke waterige oplossing geldt dat het product van de concentratie aan OH en de concentratie van H3O altijd gelijk is aan 10 mol/l.
