We are being asked to find Kb for ClO-. ClO- is the conjugate base of the weak acid HClO.

HClO   +      H2O            ClO-      +        H3O+
(weak acid)         (base)        (conjugate base)     (conjugate acid)

Hence, the Kb of ClO- can be calculated from the Ka of HClO.  Ka and Kb are connected by the autoionization constant of water (Kw) in the following equation: ###### Problem Details
