Lesson 6

Module 8—Acid-Base Equilibrium

Lesson Summary

 

In Lesson 6 you considered the following questions:

  • What information about acids and bases and their equilibrium is contained on a titration curve?
  • What events occur in the reaction of polyprotic acids and bases?

You expanded upon your understanding of pH curves you began in your previous chemistry course when you graphed the change in pH against the volume of titrant added. Your work here has helped you to read important information on a pH curve, including the following:

  • whether the substance being titrated is an acid or a base
  • whether the substance being titrated is a strong or weak acid or base
  • whether the substance being titrated is monoprotic or polyprotic

With this type of information you are able to comment on the characteristics of the acid or base being studied. If necessary, you can also design appropriate experiments for further study of the acid or base under consideration.
