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.Write the water equilibrium expression. Describe how the water equilibrium varies with pH.
