Quizplus · Accepted Answer

SrS is soluble in water because it contains a metal cation (Sr2+) and a sulfide anion (S2-), both of which can form hydration shells when dissolved in water. The other compounds contain anions that are insoluble in water, such as carbonate (CO32-), sulfate (SO42-), and oxide (O2-), or they contain cations that are not sufficiently hydrated to overcome the lattice energy of the solid.
