Kb = (Kw/Ka)
Calculate Kb for each acid, then arrange in order.
Given the table of Ka values on the right below, arrange the conjugate bases in order from strongest to weakest.
Acid Ka
HClO 3.5 e-8
HClO2 1.2 e-2
HCN 6.2 e-10
H2PO4- 6.2 e-8
A. ClO2-, ClO¬-, HPO42-, CN-
B. ClO2-, HPO42-, ClO¬-, CN-
C. CN-, HPO42-, ClO-, ClO2¬-
D. CN-, ClO-, HPO42-, ClO2-
