The spectator ion in the solution after the precipitation of an insoluble sulfate compound from AgNO3 + K2SO4 is obtained as follows

write the complete equation

that is

2 AgNO3(aq) +K2SO4(aq) = 2KNO3 (aq) + Ag2SO4(s)

the ionic equation
= 2Ag^+(aq) +2NO3^-(aq) 2k^+(aq) + SO4^2- (aq) = 2K^+(aq) + 2NO3^-(aq) + Ag2SO4(s)

the spectator ions is canceled out since they do not take place in reaction

for this case the spectator ion is 2NO3^-(aq) and 2K^+ (aq)

This ions are in aqueous state in both the product side reactant side hence they are spectator ions
