  • Acids and Alkalis
    • Acids
      • Substances that produce hydrogen ions, H+(aq), when they are added to water.
      • pH values of less than 7
      • Hydrogen ions make solutions acidic
      • Very strong acids have a pH of between 0-2
    • Alkalis
      • Bases that dissolve in water to make alkaline solutions.
      • Produce hydroxide ions, OH-(aq), in the solution.
      • pH values more than 7
      • Very strong alkalis have a pH of 12-14
    • Water
      • Neutral
      • pH value of 7
