SUMMARY
The solubility product constant (Ksp) for copper(I) sulfide (Cu2S) is calculated to be 2.5 × 10-48. This value is derived from the equilibrium expression Ksp = [Cu+]2[S2-], using the solubility of Cu2S, which is 8.5 × 10-17 M. The concentration of Cu+ is twice that of Cu2S due to the dissociation of two copper ions per formula unit. The calculations confirm the accuracy of the Ksp value.
