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: WebMar 13, 2024 · For example, you may be asked to calculate the Kb of the chloride ion. The given Ka of the conjugate acid of the chloride ion, which is hydrogen chloride, is 1.0 x 10^6. The given Kw is 1.0 x 10^-14. Write down the equation for the the Ka, the Kb, and the Kw, which is Kw = (Ka) (Kb). Solve the equation for Kb by dividing the Kw by the Ka.
