RUBIDIUM CHLORIDE RbCl

Properties Rubidium chloride RbCl:

White, melts and boils without decomposition. Readily soluble in water (without hydrolysis) and concentrated hydrochloric acid. Does not form crystalline hydrates. A weak reducing agent. Participates in exchange reactions.


Obtaining rubidium chloride RbCl:

2Rb + 2HCl(diluted) = 2RbCl + H2↑.

2Rb + E2 = 2RbE(normal temp.; E = F, Cl, Br, I).

RbOH + HCl(diluted) = RbCl + H2O,

Rb2CO3 + 2HCl (diluted) = 2RbCl + CO2 ↑ + H2O.

Rb2SO4 + BaCl2 = BaSO4↓ + 2RbCl


Сhemical reactions with rubidium chloride RbCl:

RbCl(diluted) + 6H2O = [Rb(H2O)6]+ + Cl- (pH 7).

2RbCl(solid) + H2SO4 (conc.) = Rb2SO4 + 2HCl↑ (boiling).

RbCl + RbHSO4 = Rb2SO4 + HCl (500-600°C).

10RbCl (solid) + 8H2SO4 (conc., hot) + 2KMnO4 (solid) = 5Cl2↑ + 2MnSO4 + 5Rb2SO4 + K2SO4 + 8H2O.

2RbCl + H2[SnCl6] = Rb2[SnCl6]↓ + 2HCl (in ethanol).

2RbCl + H2[PtCl6] = Rb2[PtCl6]↓ + 2HCl (in the diluted HCl).

2RbC(liquid) → Electrolysis → 2Rb (cathode) + Cl2↑(on anode).

2RbCl + 2H2O → Electrolysis → H2↑ (cathode) + Cl2↑(on anode) + 2RbOH,

2RbCl(melt, on Hg-cathode) → Electrolysis → 2Rb (on cathode) + Cl2↑(on anode).
