  1. 3-3 Solutions Acids and Bases

  2. Strengths of Acids and Bases It will depend on the number of molecules that break apart when the acid/base dissolves in water.

  3. Strong vs. weak acid • Sulfuric acid • Nitric acid • Hydrochloric acid Strong = a lot of H+ break away Weak = few molecules break apart Acetic acid Citric acid Carbonic acid

  4. Strong vs. weak base • Sodium Hydroxide • Calcium Hydroxide • Potassium hydroxide Strong = a lot of OH- are released Weak = a few molecules break apart Ammonium hydroxide Aluminum hydroxide

  5. Acid, bases, & neutralization • A + B = AB (Neutralization) • What type of reaction is this? • H+ + OH-  H2O • Other components in the reaction become salts.

  6. pH scale: Measure of the hydronium ions concentration

  7. Indicators to determine pH Compare pH paper to predetermined color charts

  8. pH and the environment Living things depend on having a steady pH in their environment.

  9. Salts • Salts are used for: • Seasoning • Making lye • Baking soda • Preserve food • Wall board • A + B = neutralization and a salt • A salt is what type of compound-covalent or ionic?
