  1. Acids, Bases, and Salts

  2. Properties of Acids and Bases

  3. Taste

  4. Foods citrus fruits yogurt and sour milk carbonated beverages vinegar Acid citric acid lactic acid carbonic acid acetic acid Acids taste sour

  5. Bases taste bitter • Like soap

  6. Touch

  7. Acids On normal skin, most dilute acids feel like water. On broken or injured skin acids can burn or sting.

  8. Bases • Bases don’t sting – except in your eyes. • Basic solutions usually feel smooth and slippery.

  9. Reactions with Metals

  10. Acids • Acids react vigorously with metals. Example: magnesium ribbon reacting with hydrochloric acid in the Ideal Gas Law Constant Lab

  11. Bases • Bases do not react with most metals.

  12. Electrical Conductivity • Both acids and bases are good conductors of electricity. • Pure water is a poor conductor of electricity, but if you add an acid or base to it will conduct electricity quite well.

  13. Indicators • An acid-base indicator is a substance that turns one color in an acidic solution and another color in a basic solution. Litmus turns red with acids and blue with bases. Phenolphthalein turns clear with acids and pink with bases.

  14. Neutralization • A reaction between an acid and a base. If the proper amounts of an acid and a base are mixed together the resulting solution will have none of the properties of the acid or the base. They in effect cancel each other out. http://www.101science.com/PH.html
