1. Identify conjugate acid-base pairs in each of the following equations:
a) HC2H3O2 + H2SO4 == H2C2H3O2+ + HSO4-
b) CH3O- + H3O+-> CH3OH + H2O
c) HCO3- + OH - === CO32- + H2O
2. Calculate [H+ ] of the following:(2)
a) a solution with a pH = 2.4.
b) [OH-] = 1.8 x 10-11
3. Calculate the pH following:
a) vinegar, 2.8 x10-3 M [H+]
b) black coffee, 5.0 x10-5 M [H+]
4. What volume in mL of0.245M HCl will neutralize 50.0 mL of 0.100M Ca(OH)2?
The equation is as follows:
2HCl (aq) + Ca(OH)2 (aq) -> CaCl2 (aq) + 2H2O (l)
5. If 29.26 mL of 0.430M HCl neutralize 20.40 mL of Ba()OH)2 solution, what is the molarity of Ba(OH)2 solution? The equation is as follows: (2)
Ba(OH)2 (aq) + 2HCl (aq) -> BaCl2 (aq) + 2H2O (l)
