ANALYZE IT

Complete the Analysis Questions in your SDR then discuss them as a class. 

  • Why are the pH values of the substances in Trial 1 all in the acidic range? 

 

  • Why are the pH values of the substances in Trial 2 all in the basic range? 
  • What is the relationship between a low pH and the hydrogen ion (H+) concentration? 
  • What is the relationship between a high pH and the hydrogen ion (H+) concentration? 
  • What would the pH of pure water be? 
  • Why is the pH of tap water not in the neutral range? 

GET FOCUSED

Complete the Focus Questions in your SDR then discuss them as a class. 

  • What properties make acids and bases chemically reactive? 
  • What is the relationship between the concentration of hydrogen ions (H+) in a solution and the chemical reactivity of strong and weak acids? 
  • What is the relationship between the concentration of hydrogen ions (H+) in a solution and the chemical reactivity of strong and weak bases?
