    • 8.2: Acid and Base Strength
      Acids and bases can be strong or weak depending on the extent of ionization in solution. Most chemical reactions reach equilibrium at which point there is no net change. The pH scale is used to succinctly communicate the acidity or basicity of a solution.
    • 8.3: Measuring Acidity in Aqueous Solutions- The pH Scale
    • 8.4: Reactions of Acids and Bases
      When an acid and a base are combined, water and a salt are the products. Salts are ionic compounds containing a positive ion other than H+ and a negative ion other than the hydroxide ion, OH-. Double displacement reactions of this type are called neutralization reactions. Salt solutions do not always have a pH of 7, however. Through a process known as hydrolysis, the ions produced when an acid and base combine may react with the water to produce slightly acidic or basic solutions.
    • 8.5: Buffer Solutions
      A buffer is a solution that resists sudden changes in pH.
