Lesson Plan: Calculating pH Chemistry

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to calculate the pH of a solution and describe the ion-product constant of water.


Students will be able to

  • recall the pH scale and identify the pH of acids, bases, and neutral solutions,
  • recall that water can self-ionize to produce HO3+ and OH ions,
  • write and describe the equation for the ion-product constant of liquid water, Kw,
  • define pH in quantitative terms as pHlog[HO]=3+,
  • relate Kw to pH and pOH,
  • calculate [HO]3+ and/or [OH] from pH and/or pOH,
  • calculate pH and/or pOH from [HO]3+ and/or [OH].


Students should already be familiar with

  • the pH scale,
  • acidity and basicity.


Students will not cover

  • dissociation constants: Ka and Kb,
  • solubility products.
