Calculate the concentrations of all species in a 0.260 M Na2SO3 (sodium sulfite) solution. The ionization constants for sulfurous acid are Ka1 = 1.4× 10-2 and Ka2 = 6.3× 10-8.Begin by assuming that sodium sulfite dissociates completely into sodium ions and sulfite ions. Since sulfite is the conjugate base of a weak acid, sulfite anion will react with water.[Na+] , [SO3 2-] , [HSO3-] , [H2SO3] , [OH-] , [H+]
