Step-by-step solution

- (A) PbS: Lead sulfide is one of the least soluble metal sulfides. Therefore, it will have the lowest (K_ s p ) value from the list. The lowest value is ((1) 4.0 10⁻⁵³ ). - (B) HgS: Mercury(II) sulfide is known to be one of the most insoluble compounds known. Its (K_ s p ) is exceptionally low. From the options, the value (II) (8.0 10⁻²⁸ ) is the next lowest, which fits. - (C) MnS: Manganese sulfide is a moderately soluble sulfide. Its (K_ sp ) is significantly higher than that of PbS or HgS, but still relatively
