Calculate the concentrations of all species in a 1.62 M Na2SO3 (sodium sulfite) solution. The ionization constants for sulfurous acid are Ka1=1.4x10^-2 and Ka2=6.3x10^-8.
Alkenes and non conjugated dienes usually have absorption maxima below 200nm. Compounds that have conjugated multiple bonds have maxima at wavelengths longer than 200nm.
