  3. Properties of Acids: • Taste sour • Contains H+, (the more H+, the stronger the acid) • Very reactive

  4. Uses of Acids: • Metal cleaners • Batteries • Digest food- found in our stomachs • Foods • Paints • Plastics

  5. Examples of Acids: • Hydrochloric acid (HCl)- in stomach • Citric acid (in citrus fruits like lemons) • Acetic acid (vinegar)

  6. Properties of Bases: • Taste bitter • Contains OH- (the more OH-, the stronger the base) • Slippery when wet

  7. Uses of Bases: • Cleansers • Drain cleaners • Soap • Shampoo • Laundry detergent

  8. Examples of Bases: • Sodium hydroxide (NaOH) • Ammonia • Lime water Ca(OH)2

  9. pH Scale • Ranges from 0-14 • Numbers 0-6 represent acids • 7 is neutral • Numbers 8-14 represent bases 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 strongest acid strongest base

  10. pH Scale • As you move from pH 0 to pH 14, the concentration of H+ DECREASES (10 times each number) • As you move from pH 0 to pH 14, the concentration of OH- INCREASES (10 times each number) • Ex: A substance with pH3 is 100 times stronger acid than a substance with pH 5. A substance with pH 8 is 100 times weaker base than a substance with pH 10.
