Question
An aqueous solution contains
ions at equal concentrations. The solubility product of
in water at
are
, respectively. Indicate which of these ions will be precipitated first and last when sulphide concentration is progressively increased from zero?
The correct answer is: 
For precipitation, ionic product > solubility product
The metal sulphide with lowest
will precipitate out first because its inonic product will exceed its
first and the metal sulphide with highest
willprecipitate out at last.
