The spectator ion is NO3- from Ba(NO3)2, as it remains unchanged throughout the reaction and does not participate in forming the precipitate of Ba3(PO4)2.
Which is a spectator ion in the reaction between Na2CO3(aq) and HNO3(aq)
In water solution potassium ion (K+) is a spectator ion, it does not react because both KOH and KBr are soluble salts (the first strongly basic, the last a neutral salt)
The spectator ions in the reaction between silver sulfate and barium nitrate are nitrate (NO3-) ions and sulfate (SO4^2-) ions. These ions do not participate in the formation of the precipitate (barium sulfate) and remain unchanged throughout the reaction.
The spectator ions for the reaction between perchloric acid (HClO4) and lithium hydroxide (LiOH) are Li+ (lithium ion) and ClO4- (perchlorate ion). These ions remain unchanged throughout the reaction and do not participate in forming the products (lithium perchlorate and water).
The molecular equation is 3Ba(NO3)2(aq) + 2(NH4)3PO4(aq) ==> Ba3(PO4)2(s) + 6NH4NO3(aq)The spectator ions are NH4^+ and NO3^-
Which is a spectator ion in the reaction between Na2CO3(aq) and HNO3(aq)
The spectator ions in this reaction are perchlorate (ClO4-) and barium (Ba2+). These ions do not participate in the reaction and remain in the solution before and after the reaction takes place.
In water solution potassium ion (K+) is a spectator ion, it does not react because both KOH and KBr are soluble salts (the first strongly basic, the last a neutral salt)
The spectator ions in the reaction between silver sulfate and barium nitrate are nitrate (NO3-) ions and sulfate (SO4^2-) ions. These ions do not participate in the formation of the precipitate (barium sulfate) and remain unchanged throughout the reaction.

The molecular equation is 3Ba(NO3)2(aq) + 2(NH4)3PO4(aq) ==> Ba3(PO4)2(s) + 6NH4NO3(aq)The spectator ions are NH4^+ and NO3^-
Na+1 and I-1; the Ba+2 and SO4-2 precipitate as BaSO4.
The net ionic equation for the reaction between HPO42- and HCl is: HPO42- + 2H+ -> H2PO4- + Cl-. The spectator ion in this reaction is Cl-.
The spectator ions in the reaction between copper (II) chloride (CuCl2) and aqueous ammonium phosphate ((NH4)3PO4) are Cl- and NH4+. These ions do not participate in the chemical reaction and remain unchanged in the solution.
There will be no reaction. These two compounds do not react with each other at all.
In the reaction between magnesium sulfate (MgSO4) and sodium hydroxide (NaOH) to form magnesium hydroxide and sodium sulfate, the spectator ions are sodium (Na+) and sulfate (SO4^2-) ions. These ions do not participate in the chemical reaction and remain in solution unchanged.
H+ and OH- could be considered the spectator ions in that reaction, although you don't typically count them, because that's just water. Really, this reaction can be summed up by saying: 2Co+3(aq) + 3SO4-2(aq) --> Co2(SO4)3(s). The precipitate is cobalt(III) sulfate.
