This chapter begins by discussing the self-ionization of water. The equilibrium constant of water is used to describe the relationship between [H30+] and [OH-]. Students will learn how pH is used to describe the concentration of acidic and basic solutions. The chapter explains how buffers are used to maintain the pH of solutions. It also presents titration as a procedure that can be used to find the concentration of an acid or base. Chapter Outline

   In this chapter, you will learn:
  • to identify the ion concentrations in pure water
  • to describe the pH scale
  • to identify a buffer
  • to explain how buffers work
  • to describe an acid-base titration
  • to explain how indicators are used in titrations and how they are chosen
