SUMMARY
The discussion centers on the solubility product constant (Ksp) for mercury(II) sulfide, represented by the equation Ksp = [Hg2+][S2-]. The calculated concentration of Hg2+ is 1.2649 x 10-26 M, which was initially believed to be correct. However, it was clarified that the presence of S2- as a strong base leads to its reaction with water, producing HS- and OH-, thereby affecting the dissolution equilibrium and invalidating the initial assumption.
