in the following total ionic equation, which ions are spectator ions?

Cu2+ (aq) + 2NO3-(aq)+2Na+(aq)+S2-(aq)--->CuS(s)+2NO3-(aq)+2Na+(aq)

  • chem -

    Spectator ions are those that are common to both sides of the equation. Cu^+2, for example, is NOT a spectator ion. It's on one side but not the other (because it formed CuS and that is not soluble.) NO3^- is a spectator ion since it is on both sides . There is another one which I will let you identify.
