What is [OH-] in a solution of 0.125 M CH3NH2 and 0.130 M CH3NH3Cl?. CH3NH2(aq)+H2O(l)CH3NH3+(aq)+OH(aq)Kb=4.4104
You have a solution of the weak acid HA and add some HCl to it. What are the major species in the solution? What do you need to know to calculate the pH of the solution, and how would you use this information? How does the pH of the solution of just the HA compare with that of the final mixture? Explain.
About this time, you may be wishing you had an aspirin. Aspirin is an organic acid with a Ka of 3.27 104 for the reaction. HC9H7O4(aq) + H2O() C9H7O4(aq) + H3O+(aq) If you have two tablets, each contains 0.325 g of aspirin (mixed with a neutral binder to hold the tablet together), and you dissolve then in a glass of water to give 225 mL of solution, what is the pH of the solution.
. Which component of a buffered solution is capable of combining with an added strong acid? Using your example from Exercise 60, show how this component would react with added HC1.
. When sodium hydroxide, NaOH, is added dropwise to a buffered solution, the _______ component of the butter consumes the added hydroxide ion.
What concentration of NH4NO3 is required to make [OH]=1.0105 in a 0.200-M solution of NH3?
Consider the following mathematical expressions. a. [H+] = [HA]0 b. [H+] = (Ka [HA]0)1/2 c. [OH] = 2[B]0 d. [OH] = (Kb [B]0)1/2 For each expression, give three solutions where the mathematical expression would give a good approximation for the [H+] or [OH]. [HA]0 and [B]0 represent initial concentrations of an acid or a base.
Explain why a buffer can be prepared from a mixture of NH4Cl and NaOH but not from NH3 and NaOH.
Could a buffered solution be made by mixing aqueous solutions of HCl and NaOH? Explain. Why isnt a mixture of a strong acid and its conjugate base considered a buffered solution?
What is [H3O+] in a solution of 0.25 M CH3CO2H and 0.030 M NaCH3CO2?. CH3CO2H(aq)+H2O(l)H3O+(aq)+CH3CO2(aq)Ka=1.8105
What is the effect on the concentration of hydro?uoric acid, hydronium ion, and fluoride ion when the following are added to separate solutions of hydrofluoric acid? (a) HCl. (b) KF. (c) NaCl. (d) KOH. (e) HF The equation for the equilibrium is: HF(aq)+H2O(l)H3O+(aq)+F(aq)
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.)
