Chlorine forms ionic bonds with almost all the metals and molecular bonds with the semimetals and nonmetals. With group 1 metals it produces well-known salts when chlorine s —1 ion combines with this group s +1 ions (e.g, NaCl, LiCl, and KCl). Group 2 metals have +2 ions and thus, when combined with —1 ions of chlorine, form salts such as magnesium chloride (MgCl ), calcium chloride (CaCy, and barium chloride (BaCy. 

It has been shown that the f.p. curves of binary mixtures of the alkali chlorides show the probable formation of compounds, LiCl.RbCl, LiCl.CsCl, and LiC1.2CsCl. The curves of binary mixtures of lithium chloride with magnesium, calcium, strontium, or barium chloride show no signs of the formation of definite compounds,... 

Lithium chloride, LiCl.—The anhydrous salt is obtained by evaporating to dryness in a current of hydrogen chloride or in presence of ammonium chloride the solution formed by dissolving the carbonate in hydrochloric acid, or decomposing the sulphate with barium chloride.4 Bogorodsky 5 has isolated three hydrates at very low temperatures the trihydrate, LiCl,3H20, is deposited in small needles at —15° C. the dihydrate, LiCl,2H20, crystallizes in cubes and at 12-5° C. octa-hedra of the monohydrate, LiCl,H20, are formed. At about 98° C. the anhydrous salt separates.

A study of the kinetics of aquation of the [IrClg] " ion at pH 1 in 3M-LiCl and 3M-LiCl-KCl shows that formation of the ion pair K+,[IrCl,] results in a slowing of the aquation reaction. Ion-pairing with barium ions, however, lowers the activation for aquation by 3.6 kcal mol to 23 kcal mol. The enthalpy and entropy of formation of the barium ion pair are reported to be 4.9 kcal mol and — 5.7 cal mol" respectively. ...
