Answer

Brief Explanations:

  • For question 21, without seeing what Label D represents, it's impossible to name the acid or base.
  • For question 22, substances with pH less than 7 are acidic. Tomatoes (pH = 4), cola drinks (pH = 3), and vinegar (pH = 5.6) have pH values less than 7.
  • For question 23, substances with pH greater than 7 are bases. Detergent (pH = 10), baking soda (pH = 8), and oven - cleaner (pH = 14) have pH values greater than 7.

Answer:

  1. Cannot be determined
  2. A. tomatoes (pH = 4), B. cola drinks (pH = 3), D. vinegar (pH = 5.6)
  3. B. detergent (pH = 10), C. baking soda (pH = 8), D. oven cleaner (pH = 14)
