calculate the ionization constant of the conjugate base for a solution made from 0.2Molar HC2H3O2 and 0.5Molar C2H3O2.The ionization constant for the acid (HC2H3O2) IS 1.8 Multiplied by 10^(-5)
I didn't know there were Kb values for solutions. The Kb for acetate ion is Kw/Ka = 1E-14/1.8E-5. I think all of the other information in the post such as M of the acid and M of the salt is superfluous.
