Problem: Which is a spectator ion from the following complete ionic equation:Ag+(aq) + NO3-(aq) + K+(aq) + Br-(aq) -> AgBr(s) + K+ (aq) + NO3- (aq)A) AgBrB) K+C) Br-D) Ag+

FREE Expert Solution

We are being asked to determine the spectator ion in the following complete ionic equation:

Ag+(aq) + NO3-(aq) + K+(aq) + Br-(aq) -> AgBr(s) + K+ (aq) + NO3- (aq)


Recall that spectator ion:

 species present on both reactant and product side
 they should have the same state, same phase, same charge
 these species are not really participating in the reaction and they are “floating around” the solution
