WebDec 30, 2024 · An example of a weak acid is acetic acid (ethanoic acid), and an example of a weak base is ammonia. Because these molecules do not fully dissociate, the pH shifts less near the equivalence point. The equivalence point will occur at a pH within the pH range of the stronger solution, i.e., for a strong acid and a weak base, the pH will be <7. 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: secondee employee meaning

HA − ⇀ ↽ − H + + A −. The equilibrium constant for this simplified reaction can be written as. Keq = [H +][A −] HA Ka = [HA]Keq = [H +][A −] pKa = − logKa. The pK a becomes a simple measure of the strength of an acid. The stronger the acid, the larger the K a and the smaller the pK a.
