I'm really struggling with the following problem, and would appreciate some guidance about how to solve it!
"A large volume of 0.150M H2SO3(aq) is treated with a solid, strong base to adjust the PH to 5.50. Assume that the addition of the base does not significantly affect the volume of the solution. Estimate the concentrations of H2SO3, HSO3-, and SO3(2-) present in the final solution. Ka1= 1.5*10-2 and Ka2= 1.2*10-7."
I've tried to use the two Ka values to write equations and solve but I keep getting the wrong answer.
Thanks in advance!
