What are the spectator ions in the solution after the precipitation of an insoluble sulfate compound from AgNO3 (aq) and K2SO4 (aq) ?

The chemical equation

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

ionic equation

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

the spectator ion is therefore = 2k^ + and 2NO3^-

therefore net ionic equation = 2Ag^ + (aq) + SO4^2 - = Ag2So4 (s)
