शिर्षक pH Scale inquiry-based intro to acid-base
वर्णन 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
