- Calculate the ionization constant for each of the following acids or bases from the ionization constant of its conjugate base or conjugate acid: (a) HTe- (as a base]. (b) (CH3)3 NH+. (c) HAsO43- (as a base). (d) H02 _ (as a base). (e) C6H5NH3+. (f) HSO3- (as a base)arrow_forward. A strong acid has a weak conjugate base, whereas a weak acid has a relatively strong conjugate base. Explain.arrow_forwardUse Table 13-3 to help answer the following questions. a. Which is the stronger base, ClO4 or C6H5NH2? b. Which is the stronger base, H2O or C6H5NH2? c. Which is the stronger base, OH or C6H5NH2? d. Which is the stronger base, C6H5NH2 or CH3NH2?arrow_forward
- Use Table 14.3 to help answer the following questions. a. Which is the stronger base, ClO4 or C6H5NH2? b. Which is the stronger base, H2O or C6H5NH2? c. Which is the stronger base, OH or C6H5NH2? d. Which is the stronger base, C6H5NH2 or CH3NH2?arrow_forwardA solution contains a mixture of acids: 0.50 M HA (Ka = 1 103), 0.20 M HB (Ka = 1.0 1010), and 0.10 M HC (Ka = 1.0 1012). Calculate the [H] in this solution.arrow_forwardThe butylammonium ion, C4H9NH3+, has a Ka of 2.3 1011. C4H9NH3+(aq) + H2O() H3O+(aq) + C4H9NH2(aq) a) Calculate Kb for the conjugate base, C4H9NH2 (butyl amine). b) Place the butylammonium ion and its conjugate base in Table 16.2. Name an acid weaker than C4H9NH3+ and a base stronger than C4H9NH3. c) What is the pH of a 0.015M solution of butylammonium chloride?arrow_forward
- How is acid strength related to the value of Ka? What is the difference between strong acids and weak acids (see Table 13-1)? As the strength of an acid increases, what happens to the strength of the conjugate base? How is base strength related to the value of Kb? As the strength of a base increases, what happens to the strength of the conjugate acid?arrow_forwardSulfanilic acid, which is used in making dyes, is made by reacting aniline with sulfuric acid. (a) Is aniline a Brnsted base, a Lewis base, or both? Explain, using its possible reactions with HCl, BF3, or other acid. (b) Sulfanilic acid has a pKa value of 3.23. The sodium salt of the acid, Na(H2NC6H4SO3), is quite soluble in water. If you dissolve 1.25 g of the salt in water to give 125 ml, of solution, what is the pH of the solution?arrow_forwardWhat is the conjugate acid of each of the following? What is the conjugate base of each?. (a) H2S. (b) H2 PO4-. (c) PH3. (d) HS-. (e) HSO3-. (f) H3O2+. (g) H4N2. (h) CH3OHarrow_forward
