WebWhen a strong base (OH-) is added to a buffer solution, the hydroxide ions are consumed by the weak acid forming water and the weaker conjugate base of the acid. The amount of the weak acid decreases while the amount of the conjugate base increases. This prevents the pH of the solution from significantly rising, which it would if the buffer WebThe conjugate base is CO 3 2 −. K b = 1 E − 14 4.7 E − 11 = 2.1 E − 4 DIscussion The Kb so calculated is for the reaction, C O 3 2 − + H 2 O ⇌ H C O 3 − + O H − K b = [ H C O 3 −] [ O H −] [ C O 3 2 −] The anion CO 3 2 − is a rather strong base, and the large value calculated for Kb agrees with the fact.
