1. An week base, aniline, has a pKb of 9.400. What is the Ka for this base? What is the Ka for the conjugate acid of the aniline (i.e. protonated aniline)?

If the Ka of the conjugate acid is 2.39 × 10-4 , what is the pKb for the base?
What is the pKb of ClO2-? Hints: What is the Ka of the conjugate acid of ClO2-? You're finding Ka then calculating pKb from that.
Aniline CoH5NH2, a weak base, has a Kb = 4.3 x 10-10 at 25°C. (a) What would be the pH of a 2.05 M solution of aniline? (8 pts) (b) What is the Ka of aniline's conjugate acid? (3 pts)
A certain base has pKb = (7.971x10^0). What is the base's Kb? (Ka, Kb, pKa, and pKb are unitless quantities.) Note: Your answer is assumed to be reduced to the highest power possible.
A certain base has pKb = (5.035x10^0). What is the base's Kb? (Ka, Kb, pKa, and pKb are unitless quantities.) Note: Your answer is assumed to be reduced to the highest power possible.
A certain base has pKb = (4.068x10^0). What is the base's Kb? (Ka, Kb, pKa, and pKb are unitless quantities.) Note: Your answer is assumed to be reduced to the highest power possible.
Consider a weak base that has a pKb of 4.2. • What is the pKa of this solution? • What is the pH of a 0.2 M solution of this base? • If you were to mix 50 mL of the 0.2 M base with 50 mL of a 0.1 M solution of its conjugate acid, what would the pH of this buffer be, and what is its effective buffering range?
What is the pKb of a weak base KA if the pH of a 0.079-M solution of KA is 9.40?
A base is found to have Kb = 7.79x10-11. What is the pKb for this acid? (Ka, Kb, pKa, and pKb are unitless quantities.)
A base is found to have Kb = 7.53x10-9. What is the pKb for this acid? (Ka, Kb, pKa, and pKb are unitless quantities.)
