Calculate the concentrations of all species in a 1.20 M Na 2 SO 3 1.20 M Na2SO3 (sodium sulfite) solution. The ionization constants for sulfurous acid are K a 1 = 1.4 × 10 − 2 Ka1=1.4×10−2 and K a 2 = 6.3 × 10 − 8

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
