The neutralization reaction between the weak acid H2S(aq)and the strong base KOH(aq) can be represented using the following total ionic equation.
2H2S+K^+ + 20H^- → 2H2O +2S^2- + K^+
From this equation, we can see that the spectator ion would be the K+ion since it is present in both sides.
Spectator ions exist on both sides of the equation in the same state because they are present during the reaction but are unaffected by it. Every neutralization reaction involves this shift.
Ions present in a reaction solution but not participating in the reaction are known as "spectator ions." As ions, they persist in solution. In this instance, both the hydride H+ and hydroxide OH1 ions from the LiOH and HBr remain in solution.
