# Problem: What is the solubility in moles/liter for copper(II) sulfide at 25 °C given a Ksp value of 1.3 x 10-36. Write using scientific notation and use 1 or 2 decimal places (even though this is strictly incorrect!)

###### FREE Expert Solution

For this problem, we’re being asked to calculate the solubility in moles/liter for copper(II) sulfide at 25 °C given a Ksp value of 1.3 x 10-36

Since the CuS is an ionic compound, it forms ions when dissociating in water. The dissociation of CuS in water is as follows:

The Sulfide ion, S2, has a charge of –2. Copper then has a charge of +2:

CuS(s)  Cu2+(aq) + S2(aq)

We can construct an ICE table for the dissociation of CuS

Remember that solids are ignored in the ICE table and Ksp expression.
