pH Scale *suitable for home teaching*
This simulation allows students to test the pH of substances like coffee, spit, and soap to determine whether each is acidic, basic, or neutral. It can be used to visualise the relative number of hydroxide ions and hydronium ions in solution, switch between logarithmic and linear scales, and investigate whether changing the volume or diluting with water affects the pH.
- Sample learning outcomes include:
- Determine if a liquid is acidic, basic, or neutral.
- Place acids or bases in relative order.
- Describe on a molecular scale, with illustrations, how the water equilibrium varies with pH.
- Determine concentration of hydroxide, hydronium and water at a given pH.
- Relate liquid colour to pH.
- Predict (qualitatively and quantitatively) how dilution and volume will affect the pH and concentration of hydroxide, hydronium and water.
