Question

Part A

Write the net ionic equation for the reaction that occurs when a solution of hydrochloric acid (HCl) is mixed with a solution of sodium formate (NaCHO_2) .

Express your answer as a chemical equation. Identify all of the phases in your answer.

Part B: Calculate the equilibrium constant for this reaction.

express using 2 sig figs

Part C:

Calculate the equilibrium concentrations of Na^+, Cl^-, H^+, CHO_2^- and HCHO_2 when 50.0mL of 0.35M NaCHO_2.

express using 2 sig figs, enter answers separated by commas

Explanation / Answer

A) HCOO-(aq) + H+(aq) <----------> HCOOH (l)

B)K = Kw/Ka(formic acid) = 10^-14/10^-3.77 = 5.89 x10^-11

C)
