Calculate the pH of a 0.14 M ammonium chloride, NH4Cl, solution. The Kb of ammonia, NH3, is 1.8 × 10−5 M.

Which of the following two acids has the stronger conjugate base? Formic acid, Ka = 1.80 x 10–4                           Hypochlorous acid, Ka = 3.0 x 10–8 Formic acid, because it has a smaller Ka Formic acid, because it has a larger Ka The strength of the conjugate base cannot be obtained from the information given. Hypochlorous acid, because it has a smaller Ka Hypochlorous acid, because it has a larger Ka

A typical aspirin tablet contains 325 mg acetylsalicylic acid. Calculate the pH of a solution that is prepared by dissolving 2 aspirin tablets in enough water to make a 269 mL solution. Assume the aspirin tablets are pure acetylsalicylic acid, K₂ = 3.3 x 10-4. Acetylsalicylic acid has a molar mass of 180 g/mol. pH = Submit Question
