Answer to Question #25163 in Physical Chemistry for ahmed

Question #25163
What are the equilibrium concentrations of H2SO3, H+, HSO3−, and SO32−in a 0.050 M solution of sulfurous acid H2SO3 at 25 oC? For H2SO3 at 25 oC, Ka1 = 1.5×10−2 and Ka2 = 1.0×10−7
Expert's answer
Concentration of H2SO3 is 0.050 M
Concentration of HSO3- is next:
The same with [SO42-]
[SO32-]=(K2*[SO42-])^1/2 = 5.26*10^-5
[H+] is the sum of this two results
