Posted by Katherine on Saturday, April 21, 2012 at 3:17pm.

Calculate the concentrations of all species in a 0.810 M Na2SO3 (sodium sulfite) solution. The ionization constants for sulfurous acid are Ka1 = 1.4 x 10^-2 and Ka2 = 6.3 x 10^-8

I calculated SO32- = 0.8096 M, HSO3- = 3.58E-4, H2SO3 = 7.1E-13, OH- = 3.58E-4, H+ = 2.79E-11
but i keep getting Na+ wrong!!! please help!
