Lesson 1

Module 8—Acid-Base Equilibrium

Lesson Summary

 

In Lesson 1 you considered the following questions:

  • What is the hydronium ion and how does it account for the properties of acidic solutions?
  • What chemical components are part of the equilibrium of water?
  • How does the equilibrium of water affect the calculation of pH?

You learned that pure water is a chemical system with an equilibrium between hydronium ions and hydroxide ions, albeit at extremely low concentrations. You used the water ionization constant to calculate the molar concentrations of [H3O+(aq)] and [OH–(aq)] that exist within water as a result of water’s equilibrium. You also reviewed the calculation of pH and pOH, further incorporating your knowledge of the equilibrium of water.
