Question
Write net Bronsted equations and determine the equilibrium constants for the acid-base reactions that occur when aqueous solutions of the following are mixed.
Instructions:
Enter all substances in the order listed at the top of the column.
Use a carot to indicate a superscript, but do nothing for subscripts.
Use a hyphen + greater than (->) for yields.

Report K to three sig figs even though it is good to only two.
Group 1A and 7A ions (except fluoride) are spectator ions.
Reactants Rxn: Acid(1) + Base(2) = Base(1) + Acid(2) K (three sig figs) hydrofluoric acid + potassium cyanide hydrochloric acid + sodium hydroxide nitrous acid + sodium fluoride KHCO3 + KCN H2SO3 + K2SO4Explanation / Answer
HF + KCN-------- KF + HCN Keq = [KF][HCN] / [HF][KCN]
HCl+ NaOH-------- NaCl+ H2O Keq = [NaCl][H2O] / [HCl][NaOH]
HNO2+ NaF-------- NaNO2+ HF Keq = [NaNO2][HF] / [HNO2][NaF]
KHCO3 + KCN--------- K2CO3 + HCN Keq = [K2CO3][HCN] / [KHCO3][KCN]
H2SO3 + K2SO4 --------K2SO3 + H2SO4 Keq = [K2SO3][ H2SO4] / [H2SO3][K2SO4]
