Select one:
a. H3O+(aq) + OH–(aq) → 2H2O(l)
b. OH–(aq) + HCHO2(aq) → CHO2–(aq) + H2O(l)
c. NaOH(aq) + H3O+(aq) → Na+(aq) + 2H2O(l)
d. NaOH(aq) + HCHO2(aq) → NaCHO2(aq) + H2O(l)

The salt sodium formate, NaCHO2(s), completely dissociates into Na+(aq) and CHO2−(aq) in an aqueous environment. The Na+ ion has no acid or base properties, but the formate ion is the conjugate base of the weak acid, formic acid. Part a. Write a balanced chemical equation showing how the formate ion reacts with water to affect the pH of the resulting solution (you can ignore the sodium ion in your balanced equation). Part b. Find the pH of a 0.100 M...
(4) 6 pts. A buffer contains 0.500 M of Formic acid (HCHO,) and 0.500 M of sodium formate (NaCHO2). Formic acid is a weak acid that dissociates in water as following: HCHO2 (aq) + H20 (1) =H30+ (aq) + CHO2 (ag) The equilibrium constant: Ks = ([H30+1X[CH02:])/[HCH02] =1.8 x 10-4 Calculate the pH of the buffer solution.
