Respuesta :
If sodium sulfide is added to iron(II) sulfide, no reaction could occur since they have a common ion. Instead, in the solution, the concentration of Fe2+ would decrease while the concentration of S2- would increase since more of this ion is added from sodium sulfide.
Answer:
[Fe2+] decreases and [S2–] increases because sulfide is a common ion.
