Problem 32E
Explain the following observations: (a) NH3 contains no OH– ions, and yet its aqueous solutions are basic; (b) HF is called a weak acid, and yet it is very reactive; (c) although sulfuric acid is a strong electrolyte, an aqueous solution of H2SO4 contains more HSO4– ions than SO42– ions.
ANSWER:
(a) When NH3 interacts with water, it produces ammonium (NH4+) and hydroxide (OH-) ions due to its polar nature. The OH- ions will react with the H+ ions in the water to form H2O molecules, meaning that the overall solution will be basic.
(b) HF is called a
