WebOct 28, 2024 · Answer: pH = 11.9 Explanation: The solution is 0.93M. The pKb is 4.19 The general equation of a weak base, X, is: Kb = [OH⁻] [XH⁺] / [X] Where Kb is 10^-pKb = 6.457x10⁻⁵ [OH⁻] and [XH⁺] comes both from the same equilibrium and its concentration, X, is the same = [OH⁻] = [XH⁺] = X WebJan 30, 2024 · Through the use of the Lewis definition of acids and bases, chemists are now able to predict a wider variety of acid-base reactions. Lewis' theory used electrons instead of proton transfer and specifically …
