WebThe titration involved in the determination of the carbonate content is an example of a weak base being titrated with a strong acid. The two weak bases involved are CO2 − 3 with Kb1 = 2.1 × 104 and HCO − 3 with Kb2 = 2.4 × 10 − 8. The reactions involved are: CO2 − 3 + H3O + ⇌ HCO − 3 + H2O. and. WebThe pH of a salt solution is determined by the relative strength of its conjugated acid-base pair. Salts can be acidic, neutral, or basic. Salts that form from a strong acid and a weak base are acid salts, like ammonium chloride (NH4Cl). Salts that form from a weak acid and a strong base are basic salts, like sodium bicarbonate (NaHCO3). Sort by:
