• 9.1: Acid and Base Strength
Acids can be classified as strong or weak based on the extent to which they produce H3O+ when dissolved in water.
• 9.2: Buffers
A buffer is a solution of a weak acid or a base and its salt. Both components must be present for the system to act as a buffer to resist changes in pH. The salt is the conjugate of the weak acid or of the weak base.
• 9.E: Equilibrium Applications (Exercises)
These are homework exercises to accompany Chapter 9 of the University of Kentucky's LibreText for CHE 103 - Chemistry for Allied Health. Solutions are available below the questions.
