Chlorine

  1. Compounds of chlorine

Cl2reacts with active metals without heating, with other substances when heating:

2Sb + 5Cl2 2SbCl5

Cu + Cl2 CuCl2

Important feature: at complete absence of moisture Cl2 has no action on iron, therefore liquefied gas Cl2can be stored in steel bulbs.

Cl2is astrong oxidant. It reacts with non-metals, forming covalent chlorides:

2P + 5Cl2 = 2PCl5

2NH3 + 3Cl2 = N2 + 6HCl

Interaction of Cl2with H2is an interesting example of the unbranched chain reaction:

Cl2 + Hn = 2Cl

Cl + H2 HCl + H

H + Cl2 HCl + Cland etc.

Here a single excited (?) Cl2 molecule forms on the 100 thousand HCl molecules in average.

Highly explosive oil-likechloride of nitrogen, NI3, Is formed in the concentrated solution of NH4Cl:

NH4Cl + 3Cl2 = NCl3 + 4HCl

Chlorine has a positive charge in 3 molecule. Chlorine gas demonstrates reducing propertiesonly at interaction with F2:

3F2 + Cl2 = 2

Reaction of chlorine with the halogens.Fluorine, F2, Reacts with chlorine, Cl2, At 225 C to form the interhalogen species C1F. Chlorine (III) fluoride is also formed and the reaction does not reach its completion.

Cl2(G) + F2(G) = 2ClF (g) 225oC

Cl2(G) + 3F2(G) = 2ClF3(G)

Under more forcing conditions, excess fluorine reacts withchlorine, Cl2, At350 C and 225 atmospheres pressure to form the interhalogen species C1F5.

Cl2(G) + 5F2(G) = 2ClF5(G) 350oC, 225atm

Chlorine, Cl2, Reacts with bromine, Br2, In the gas phase to form the unstable interhalogen species bromine (I) chloride, ClBr.
