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: Webp H = p K a + log ( [ C H X 3 N H X 2] [ C H X 3 N H X 3 X +]) 10.00 = 10.64 + log ( 10 m m o l x) where x is the amount of H C l that must be added.
