CESIUM CHLORIDE CsCl

Properties of cesium chloride CsCl:

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

 

Obtaining cesium chloride CsCl:

2 Cs + 2HCl (diluted) = 2 CsCl + H2↑.

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

CsOH + HCl (diluted) = CsCl + H2O,

2 CsOH + H2SO4 (diluted) = Cs2SO4 + 2 H2O,

CsOH + HNO3 (diluted) = CsNO3 + H2O.

Cs2CO3 + 2 HCl (diluted) = 2 CsCl + CO2↑ + H2O.

Cs2SO4 + BаE2 = BaSO4↓ + 2 CsE (E = Cl-, OH-).

 

Сhemical reactions with cesium chloride CsCl:

CsCl (diluted) + 6H2O = [Cs(H2O)6]+ + Cl- (pH 7).

2 CsCl (solid) + H2SO4 (conc.) = Cs2SO4 + 2HCl↑ (кип.).

CsCl + CsHSO4 = Cs2SO4 + HCl (550—700° C).

10 CsCl (solid) + 8H2SO4 (conc., hot) + 2KMnO4(solid) = 5 Cl2↑ + 2 MnSO4 + K2SO4 + 5 Cs2SO4 + 8 H2O.

2 CsCl + H2[SnCl6] = Cs2[SnCl6]↓ + 2 HCl (in the conc. HCl).

3 CsCl + 2H[SbCl4] = Cs3[Sb2Cl9]↓ + 2 HCl (in the conc. HCl).

2 CsCl + H2[PtCl6] = Cs2[PtCl6]↓ + 2 HCl (in the diluted HCl).

2 CsCl (liquid) →Electrolysis 2Cs(cathode) + Cl2↑ (anode).

2 CsCl + 2 H2O →Electrolysis H2↑ (cathode) + Cl2↑ (anode) + 2 CsOH,

2 CsCl (melt) (on Hg-cathode)→Electrolysis 2 Cs (cathode) + Cl2↑ (anode)./p>
