Identify the spectator ions in the following molecular equation. KBr(aq) + AgNO3(aq) → AgBr(s) + KNO3(aq).

Chemistry

In aqueous solutions, soluble salts will dissociate into ions. Since all salts of nitrates are completely soluble in water, AgNO3 and KNO3 will dissociate into Ag+, K+, and NO3- ions. KBr is also soluble in water, forming K+, Br- ions.

Rewriting the equation:

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

Spectator ions are those that does not participate in the reaction, which means they are found in both sides in the equation above. K+ and NO3- are those ions.
