Identify the spectator ions in the following molecular equation.
KBr(aq) + AgNO3(aq) → AgBr(s) + KNO3(aq)
I'm not sure what the rules are for assigning oxidation numbers.

we can rewrite the equation KBr(aq) + AgNO3(aq) → AgBr(s) + KNO3(aq) into its net ionic equation into
 K+ + Br- + Ag + + NO3-  = AgBr + K + NO3-only aqueous solutions can dissociate. Spectator ions are present in both sides, hence these are K+ and NO3-. THe rules of assigning oxidation numbers is to identify the number of valence electrons of elements and may be arbitrary depending on the charge of the molecule. 

The identification of the spectator ions should be K+ and NO3-

Identification of the  spectator ions:

Here the chemical equation should be written again in the net ionic equation

KBr(aq) + AgNO3(aq) → AgBr(s) + KNO3(aq)

K+ + Br- + Ag + + NO3-  = AgBr + K + NO3-

Here only aqueous solutions should be dissociated. Also, Spectator ions should be present in both sides, so these are K+ and NO3-. The rules of assigning oxidation numbers are to identify the number of valence
