Concept explainers
Interpretation:
The pH of the solution with dissolved salts is to be predicted.
Concept introduction:
Salt is a strong electrolyte that dissociates completely when added to water.
When a salt contains a cation that comes from a weak base then the cation recombines with water to produce a weak base and hydronium ions, and forms an acidic solution.
When a salt contains an anion that comes from a weak acid then the anion recombines with water to produce a weak acid and hydroxide ions, and forms a basic solution.
The anion, if it comes from a strong acid, does not recombine and is present in the solution as a free ion without having any effect on the pH of the solution.
The cations that are highly charged and have a small size will form acidic solutions.
The cations from group 1A and selective cations of group 2A, along with the ones from strong bases will form a neutral solution.

- For conjugate acidbase pairs, how are Ka and Kb related? Consider the reaction of acetic acid in water CH3CO2H(aq)+H2O(l)CH3CO2(aq)+H3O+(aq) where Ka = 1.8 105 a. Which two bases are competing for the proton? b. Which is the stronger base? c. In light of your answer to part b. why do we classify the acetate ion (CH3CO2) as a weak base? Use an appropriate reaction to justify your answer. In general, as base strength increases, conjugate acid strength decreases. Explain why the conjugate acid of the weak base NH3 is a weak acid. To summarize, the conjugate base of a weak acid is a weak base and the conjugate acid of a weak base is a weak acid (weak gives you weak). Assuming Ka for a monoprotic strong acid is 1 106, calculate Kb for the conjugate base of this strong acid. Why do conjugate bases of strong acids have no basic properties in water? List the conjugate bases of the six common strong acids. To tie it all together, some instructors have students think of Li+, K+, Rb+, Cs+, Ca2+, Sr2+, and Ba2+ as the conjugate acids of the strong bases LiOH, KOH. RbOH, CsOH, Ca(OH)2, Sr(OH)2, and Ba(OH)2. Although not technically correct, the conjugate acid strength of these cations is similar to the conjugate base strength of the strong acids. That is, these cations have no acidic properties in water; similarly, the conjugate bases of strong acids have no basic properties (strong gives you worthless). Fill in the blanks with the correct response. The conjugate base of a weak acid is a_____base. The conjugate acid of a weak base is a_____acid. The conjugate base of a strong acid is a_____base. The conjugate acid of a strong base is a_____ acid. (Hint: Weak gives you weak and strong gives you worthless.)arrow_forwardThe major component of vinegar is acetic acid, CH3COOH.
