Calculate the concentrations of all species present in 0.14 M H2SO3. (Ka1=1.5×10−2, Ka2=6.3×10−8). Calculate the concentration of H2SO3, HSO3- , H3O+, SO32- in solution.
A large volume of 0.150M Sulfurious Acid (H2SO3) is treated with a strong base to adjust the pH to 5.50. Assume that the additions of the base, a solid, does not significantly affect the volume of the solution. Estimate the molar concentration of H2SO3, HSO3(-), SO3 (2-) present in the final solution. Ka1 = 1.5 x 10^-2 Ka2 = 1.2 x 10^-7 Answers are H2SO3 = .000032 M HSO3(-)=.14 M SO3 (2-) = .0054 M
