Homework Help: Chemistry

Posted by Chris on Thursday, October 11, 2012 at 7:40pm.

Calculate the concentrations of all species in a 1.41 M Na2SO3 (sodium sulfite) solution. The ionization constants for sulfurous acid are Ka1 = 1.4 102 and Ka2 = 6.3 108.

Na^+ = 2.82M
SO3^2- = 1.40M
HSO3^- = 0.00047M
H2SO3 =
OH^- =
H^+ =

I have been able to calculate the first three, but do not know where to go from there to find the last three. Any help would be very much appreciated.
