Question:

calculate all the concentration of all species in a 0.800 M Na2SO3 (sodium sulfite) solution. The ionization constants for sulfurous acid are Ka1 = 1.4E-2 and Ka2 = 6.3E-8.

Na+,SO32-,HSO3-,H2SO3,OH-,H+

ionization Constant:

The ionization constant of the weak acids have lower value as compared to the ionization constant of the strong acid. The diprotic acids have two acid dissociation constant. The first acid dissociation of the diprotic acids have a higher value as compared to the second acid dissociation constant value.
