PROBLEM 28 a. Which is a stronger acid, one with a pK₁ of 5.2 or one with a pK₁ of 5.8? b. Which is a stronger acid, one with an acid dissociation constant of 3.4 × 10-³ or one with an acid dissociation constant of 2.1 x 10-4? PROBLEM 29. An acid has a K₁ of 4.53 × 106 in water. What is its Keq? ([H₂O] = 55.5 M) PROBLEM 30 a. For each of the acid-base reactions in Section 1.17, compare the pK₁ values of the acids on either side of the equilibrium arrows and convince yourself that the position of equi- librium is in the direction indicated. (The pK₁ values you need can be found in Section 1.17 or in Problem 31. b. Do the same thing for the equilibria in Section 1.16. (The pK₂ of *NH4 is 9.4.)
