Ph with kb

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: WebCompare the values of the base dissociation constant for ammonia and methylamine: K b (ammonia) = 1.8 × 10-5 (smaller) . K b (methanamine) = 4.4 × 10-4 (larger) . At 25°C, using solutions of the same concentration, for example 0.1 mol L-1: (i) There will be more undissociated ammonia molecules than undissociated methylamine molecules.
