14. a. Acidic

15. b. Weaker

16. d. Dilute and weak

Explanation:

14. Which type of the solution is one with the pH of 3?

Solution with pH from 1 to 7 are acidic, equal to 7 is neutral and from 7 to 14 basic. The solution with the pH equal to 3 is <u>acidic</u>.

15. The smaller the value of the base dissociation constant (Kb), the <u>weaker</u> the base.

The dissociation reaction of a base (B) is:

B + H₂O → BH⁺ + OH⁻

Kb is defined as:

Kb = ( [BH⁺] × [OH⁻] ) / ( [B] × [H₂O] )

The potency of the base depends on the concentration of the hydroxide ion [OH⁻], so if the Kb ratio is small it means that the concentration of hydroxide ion is smaller so the base will be <u>weaker</u>.

16. A 0.39 M solution of an acid that ionizes only slightly in solution would be termed <u>dilute and weak</u>.

The acid is weak because is only slightly ionizing in solution. The therm diluted is a little bit arbitrarily because we ask yourself "diluted in respect with what"? I would characterize the acid to be diluted at a concentration of 1 M and concentrated at a concentration of 10 M.
