Respuesta :
The spectator ions of when k2s and mgcl2 are combined are 1. Cl- (aq) and 2. K (aq)
the balance equation of MgCl2 and K2S is as follows:
MgCl2(aq) + K2S(aq) ------> MgS(s) + 2KCl(aq)
the net ionic equation is as follows:
Mg 2+ (aq) + 2 Cl- (aq) + 2K (aq) + S 2- (aq) = MgS(s) +2 Cl- (aq) + 2K (aq)
The overall reaction is as follows:
Mg 2+ (aq) + S 2- (aq) = MgS(s)
Thus the spectator ions are the following:
Cl- (aq)
K (aq)
If we compare the solutions before and after the reaction, sodium and nitrate ions are present in both the solutions. They do not undergo any chemical exchange at all. These ions are called spectator ions since they don't participate in the chemical reaction at all (they simply "watch").
Compare the reactant and product sides of the rewritten reaction and cross out the spectator ions. Any dissolved ions that appear in the same form on both sides are spectator ions.
