CALCULATE THE pH Of A Weak
Base
Triethylamine, N(C2H5)3, has a solubility of 68.6gL, a molar mass
of 101.19gmol, and a base-ionization constant Kb=6.0×10-4. What is
the pH of a saturated solution of triethylamine in water?
Use pKw=14.00 for the ion-product of water.
Round your answer to two decimal places.
pH=12.30
Ammonia, NH3, is a weak base that is often used in household cleaning
solutions. What is the pH of a solution of ammonia that contains 5.0g of
ammonia in 709mL of solution? The molar mass of ammonia is 17.03gmol,
and its base-ionization constant is 1.8×10-5.
Round your answer to two decimal places.
pH = 11.44
A weak base has Kb=3.2×10-6. The compound has a solubility of 1.667gL, and the
molar mass is 303.36gmol. What is the pH of a saturated solution of this compound?
Use pKw=14.00 for the ion-product of water.
Round your answer to two decimal places.

Aniline, C6H5NH2, is a very weak organic base that is used in the production of
antibacterial sulfa drugs. The Kb of aniline is 4.0×10-10. If 0.110mol of
aniline is added to water to make up 0.325L of solution, what is the pH of the
resulting solution?
Round your answer to two decimal places.
