How do weak bases dissociate in water
WebFeb 2, 2024 · Weak bases react with water to produce the hydroxide ion, as shown in the following general equation, where B is the parent base and BH+ is its conjugate acid: B(aq) + H 2O(l) − ⇀ ↽ − BH + (aq) + OH − (aq) The equilibrium constant for this reaction is the … WebNov 1, 2024 · Ammonia is perhaps the most common weak base of all. Its dissociation in water can be schematized as follows: NH 3 (ac) + H 2 O (l) <=> NH 4+ (ac) + OH – (ac) Therefore, NH 3 It falls into the category of bases represented by 'B'. The dissociation constant of ammonia, K b, is given by the following expression: K b = [NH 4+] [OH –] / [NH 3]
