- Calculate the Kb value for the conjugate base of hydrosulfuric acid. The Ka for H2S is 9.6 x 10-8What is Kb for the conjugate base of CH₃COOH (Ka = 1.8 × 10⁻⁵)?Put the following bases in order from weakest to strongest and explain why. Cute specific pKa values of conjugate acids to answer this question.
- If the Ka of the conjugate acid is 5.06 × 10-5 , what is the pKb for the base?Which of the following two acids has the stronger conjugate base? Nitrous acid, Ka = 7.1 x 10–4 Phenol, Ka = 1.0 x 10–10 The strength of the conjugate base cannot be obtained from the information given. Nitrous acid, because it has a larger Ka value. Nitrous acid, because it has a smaller Ka value. Phenol, because it has a larger Ka value. Phenol, because it has a smaller Ka value.Use the Kb for the nitrite ion, NO2−, to calculate the Ka for its conjugate acid.
- Benozic acid (C6H5COOH) has a pKa of 4.20. a. What is the ratio of the acid to its conjugate base at a pH of 2.20?What is the conjugate base of H2S?Why is HCl so acidic? For example, why is H-Cl more acidic than H-S-CH3? Isn't the conjugate base's negative charge more stabilized with a sulfur and extra methyl group (by the induction effect)? While Cl is more electronegative than Sulfur, I would assume Cl being alone as its own ion would make it less stable.
