WebSolution. The Ka for oxalic acid is. K a = 1 E − 14 1.8 E − 10 = 5.6 E − 5. DIscussion. The calculation regarding Ka and Kb conversion is simple, but understanding what problems require this type of conversion is difficult. The concept is rather useful, and it further … WebK a = K w / K b or K b = K w / K a. The inverse proportional relation between Ka and Kb means the stronger the acid or base, the weaker its conjugate partner. Figure 14.7 illustrates this relation for several conjugate acid-base pairs. Figure 14.7 Relative strengths of several conjugate acid-base pairs are shown.

WebTo identify conjugate acid base pairs remember there's only one proton or one H plus difference between an acid and it's conjugate base. So when HA donates its proton and turns into A minus, A minus must be the conjugate base to HA. So there's one H plus difference between HA and A minus. They are a conjugate acid base pair.

WebWeak acids and the acid dissociation constant, K_\text {a} K a. Weak acids are acids that don't completely dissociate in solution. In other words, a weak acid is any acid that is not a strong acid. The strength of a weak acid depends on how much it dissociates: the more it dissociates, the stronger the acid. WebThe relationship between the acid dissociation constant (K a) and the base dissociation constant (K b) for a conjugate acid-base pair is given by the equation: K a × K b = K w Explanation:

WebThe relationship between Ka and Kb for any conjugate acid-base pairs is as follows: (K a)(K b) = K w. Where K a is the ionization constant of the acid form of the pair, K b is the ionization constant for the base form of the pair, and K w is the ionization constant for water. This equation is used to find either K a or K b when the other is known. WebNov 5, 2024 · Determine the value for the Kb and identify the conjugate base by writing the balanced chemical equation.
