The oxidation number of rubidium in rubidium iodide is 1.

Synthesis

Ane way to make rubidium iodide is to react the hydroxide with hydroiodic acrid. The resulting salt can and so be purified past recrystallization.

RbOH(aq) + HI(aq) → RbI(aq) + H₂O(fifty)

Rubidium(I) iodide can also exist made by the neutralization of rubidium(I) carbonate with hydroiodic acrid. The resulting common salt can then be purified by recrystallization.

Rb₂(CO₃)(aq) + 2HI(aq) → 2RbI(aq) + H_iiO(l) + CO₂(g)

While not a normal road of preparation considering of the expense, rubidium metal reacts vigorously with all the halogens to form rubidium halides. So, information technology burns with iodine, I_two, to form rubidium(I) iodide, RbI.

2Rb(south) + I_ii(southward) → 2RbI(s)
