Question

1. name the acid or base for label d.
2. identify all the substances that are acidic.

a) tomatoes (ph = 4)
b) cola drinks (ph = 3)
c) oven cleaner (ph = 14)
d) vinegar (ph = 5.6)
e) toothpaste (ph = 9)

1. identify all the substances that are a base.

a) milk (ph = 6.5)
b) detergent (ph = 10)
c) baking soda (ph = 8)
d) oven cleaner (ph = 14)
e) tomatoes (ph = 4)

Explanation:

• 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)
