When solutions of barium iodide and lithium sulfate are mixed,the spectator ions in the resulting precipitation reaction are

Question

Quizplus · Accepted Answer

The chemical equation for the reaction between barium iodide and lithium sulfate is:

BaI2 + Li2SO4 → BaSO4 + 2 LiI

In the equation, the ions that do not participate in the reaction and remain in solution are called spectator ions. These ions are not changed chemically and do not affect the precipitation that occurs.

In this reaction, the spectator ions are Li+ and SO42- because they appear on both sides of the equation. The ions that are involved in the reaction and form the precipitate are Ba2+ and I-. Therefore, the answer is choice B, both Li+ and SO42- are spectator ions.
