PH worksheet (#1). Chemistry Chapter Acids and Bases. (Self-Ionization of Water) H 2 O + H 2 O H 3 O + + OH - Two water molecules collide to form Hydronium and. Ways to measure Acidity/Basicity What is pH? What is pOH?
The definition of pH and its measurement is well-developed for aqueous solutions; however, the determination of pH in non-aqueous solutions is less defined. Numerous functions, theories, and calculations have been developed over the years to indicate the acidity/basicity of non-aqueous or strongly...
