We have a solution that is in equilibrium with solid Ag2SO3 (ksp=1.5x10^-14), and buffered at pH=8.00. The sulfite anion (SO3(2-)) is the conjugate base of the bisulfite anion (HSO3-), which is the conjugate base of sulfurous acid (H2SO3) a diprotic weak acid (Ka,1=1.23x10^-2,Ka,2=6.6x10^-8).
a. Set up the problem by listing the reactions, unknowns, equations and knowns.
b. Calculate the concentrations of all chemical species present in the solution, and the pH.
