Weak bases. Ammonia is a typical weak base. Ammonia itself obviously doesn't contain hydroxide ions, but it reacts with water to produce ammonium ions and hydroxide ions. \[ NH_{3(aq)} + H_2O_{(l)} \rightleftharpoons NH^+_{4(aq)} + OH^-_{(aq)}\] Sulphuric acid is a strong acid, while zinc hydroxide is a weak base, hence, the solution is acidic in nature. Question 8: An aqueous solution of ammonium acetate, neutral in nature. Why? Answer: Ammonium acetate, when dissolved in water is hydrolysed to form ammonium hydroxide and acetic acid. Ammonium hydroxide and acetic acid both are weak Unlike strong acids/bases, weak acids and weak bases do not completely dissociate (separate into ions) If you want to test this by making an ICE table, you should get that the total hydroxide concentration is 0.0207000222 M \approx 0.0207 M. so pOH = -log(0.0207) = 1.68. pH + pOH = 14 The alkoxides are stronger bases that are often used in the corresponding alcohol as solvent, or for greater reactivity in DMSO. Finally, the two amide bases see widespread use in generating enolate bases from carbonyl compounds and other weak carbon acids. In addition to acting as a base, 1 o and 2 o amines can act as very weak acids. Their N Dịch Vụ Hỗ Trợ Vay Tiền Nhanh 1s.
