Copper (II) sulfide (CuS) is only slightly soluble in water (Ksp= 1.27 x 10-36). A scientist has prepared 300.00 mL of a saturatedaqueous solution of copper (II) sulfide for theirexperiments.
a. What is the concentration, in molarity, of sulfide ion thesolution described above?

b. What would the concentration, in molarity, of sulfide be if4.0051 g of copper (II) nitrate was added to the solution describedat the beginning of the question? (assume the volume added to thesolution is negligible).

c. Given the two molar solubility calculations done in parts aand b, would any copper (II) sulfide precipitate? If so, calculatethe grams of copper (II) sulfide that precipitates?
