1. Quantitative Relationship between Ka and Kb of Conjugate Acid-Base Pairs
The learning resource Relative Strength of Acids and Bases will illustrate to you the quantitative relationship between Ka and Kb. Moreover, you will be able to know the relative strengths of acids and bases. After reading this learning resource, you will be familiarized to the strong and weak acids, strong and weak bases, know the concept of “levelling effect” and know how to calculate problems that involve Ka, Kb and Kw.
2. Self-test
What is the Kb
for the equilibrium below where Ka is 6.2 × 10-10 at 25oC?
CN- + H2O ⇌ HCN + OH-
Ans: Kb = 1.6 × 10-5
