17. Acid and Base Equilibrium

If the Kb of NH₃ is 1.76 x 10^-5, determine the acid dissociation constant of its conjugate acid. 

Which Bronsted-Lowry base has the greatest concentration of hydroxide ions? 

Which Bronsted-Lowry acid has the weakest conjugate base?

The following diagrams represent aqueous solutions of three acids, HX, HY, and HZ. The water molecules have been omitted for clarity, and the hydrated proton is represented as H+ rather than H3O+.(b) Which acid would have the smallest aciddissociation constant, Ka?

Classify each acid as strong or weak. If the acid is weak, write an expression for the acid ionization constant (K_a). d. H₂CO₃

The following pictures represent solutions of three salts NaA (A- = X-, Y-, or Z-); water molecules and Na+ ions have been omitted for clarity.

(c) Which A- anion has the smallest value of pKb?

The following picture represents the hydrated metal cation M1H2O26 n + , where n = 1, 2, or 3.

(a) Write a balanced equation for the reaction of M1H2O26 n + with water and write the equilibrium equation for the reaction.
