Percent dissociation can be used to calculate Ka!

Predict whether an aqueous solutions of the following salts will be acidic, basic or neutral:

NH4C2H3O2Ka for NH4

+ = 5.6 x 10-10, Kb for C2H3O2- = 5.6 x 10-10

NH4CNKa for NH4

+ = 5.6 x 10-10, Ka for HCN = 6.3 x 10-10

Al2(SO4)3Ka for Al(H2O)6

3+ = 1.4 x 10-5, Ka2 for H2SO4 = 1.2 x 10-2
