Consider the following precipitation reaction: Pb(NO3)2(aq) + 2KI(aq) → PbI2(s) + 2KNO3(aq). Which ions are spectator ions? pls

Marta_Voda [28]

Potassium and Nitrate ions are spectator ions in the reaction:

$Pb(NO_3)_2(aq) + 2KI(aq)$ → $PbI_2(s) + 2KNO_3(aq).$

<h3>What are spectator ions?</h3>

Ions that are not involved in the actual chemical reaction are called spectator ions.

A precipitation reaction occurs when two ionic compounds react to produce a precipitate and an insoluble substance which stays in the solution as a spectator ion.

Hence, Potassium and Nitrate ions are spectator ions in the reaction:

$Pb(NO_3)_2(aq) + 2KI(aq)$ → $PbI_2(s) + 2KNO_3(aq).$
