What, if any, are the spectator ions when aqueous solutions of HBr and RbOH neutralize each other? A)H ⁺ and OH ⁻ B)H ⁺ and Rb ⁺ C)Rb ⁺ and Br ⁻ D)Br ^- and OH ⁻ E)There are no spectator ions in this reaction.

Question

Quizplus · Accepted Answer

Spectator ions are ions that do not participate in the chemical reaction and remain in solution unchanged. In the neutralization of HBr with RbOH, the H+ from HBr reacts with the OH- from RbOH to form water, leaving Rb+ and Br- as spectator ions.
