pH Scale inquiry-based intro to acid-base |
Popis
|
These are inquiry based activities to introduce pH. In 2020, Remote versions were added for students working at home using the HTML5 sim.
Learning goals: Determine if a solution is acidic or basic using pH; H3O+/OH- ratio (molecular size representation of just the ions in the water equilibrium);Hydronium/Hydroxide concentration
2.Relate liquid color to pH.
3.Predict if dilution and volume will increase, decrease or not change the pH
4.Organize a list of liquids in terms of acid or base strength in relative order with supporting evidence.
5. Determine if a solution is acidic or basic using
molecular size representations
H3O+/OH- ratio
Hydronium and/or Hydroxide concentration
6. Relate pH to H3O+/OH- ratio, Hydronium and/or Hydroxide concentration |
