how do you identify spectator ions in redox equations?
I understand everything about redox equations like oxidation and reduction how to balance them. Balance the electrons and balance them in acidic and basic solution. But how do you identify spectator ions? Like I know that when an element such as Na is attached to dichromate =
Na2Cr2O7 -2 we must eliminate the Na. I know this but how about this problem:
AuCl3 + NaI > Au + I2 + NaCl
my teacher eliminated all Cl and Na
so AU + I > Au + I2 (why??? eliminate Na and Cl is it because they dont change oxidation states in the reaction???)
why does this occur? ANY help please would be great

Yes, because they are both spectator ions, I believe. I think that it is because they do not change oxidation states like you said. I think that you do identify spectator ions by seeing which ones are not oxidized or reduced. I hope this helps!!!
