under a certain set of conditions the solubility of Ag2CO3 is 3.5x10^-2 g/L. what is the ksp?

Solutions

Expert Solution

A:- Ionization of Ag2CO3 gives,

                         Ag2CO3 ------>    2 Ag+ +    CO32-

                                                       (2S)           (S)

                    Ksp = [Ag+]2 * [CO32- ]

                        Ksp = (2S)2 * S                                                ( since S = 3.5*10^-2 g/L )

                                  = 4 S3

                                     = 4 * ( 3.5 * 10-2 )3

                                Ksp = 1.7 * 10-4
