Acids and Bases

• Analyze Data What color range did the
  substances show when tested with the indicator
  paper? What do your results tell you about the

• Classify Look for patterns in the pH values.
  Use your test results to place each household
  substance in one of three groups acids, bases,
  or neutral
• Model Draw a diagram of the pH scale from 0 to
  14. Illustrate where the substances you tested
  fall on this scale

Conclude

• Generalize What general conclusions can you
  draw about the hydrogen ion concentration in many
  acids and bases found in the home? Are the
  hydrogen ion concentrations very high or very
  low? How do you know?
• Evaluate What limitations or difficulties did
  you experience in interpreting the results of
  your tests or other observations?
• Apply Antacid tablets react with stomach acid
  containing hydrochloric acid. What is this type
