Which ions are spectator ions in the formation of a precipitate of agcl via combining aqueous solutions of cocl2 and agno3?

AgNO3 reacts with CoCl2 based on the following equation:

AgNO3 + CoCl2 ... > CoNO3 + AgCl 2

The complete ionic equation for this reaction is:

Co2 + (aq) + 2Cl - (aq) + 2Ag + (aq) + 2NO3 - (aq) ... > 2AgCl (s) + Co2 + (aq) + 2NO3 - (aq)

while the net ionic equation is:

Cl - (aq) + Ag + (aq) → AgCl (s)

From this ionic equations, we can see that Co2 + and NO3 - remained unchanged in the ionic equations. Therefore Co2 + and NO3 - are the spectator ions.
