Determine the Effect of Hydrolysis in Producing Acids or Bases.
- Determine relative pH and strength of various salt solutions
- Requires one 50 minute class period
Students discover how and why salts vary in neutrality as they determine actual acidity or basicity of different salt solutions. With the use of the Chemplates® each student tests seven different salt solutions for pH, predicts relative strength, and determines whether the salt hydrolyzed in water produces an acidic or basic solution. This is all done through observation.
