Thermal studies on halides and basic halides of copper(II)

Abstract

The thermal decomposition of the halides and basic halides of copper(II) have been studied by a thermogravimetric method. The hydrated chloride loses water and then halogen to give the copper(I) compound which then oxidises to copper(II) oxide; the bromide behaves similarly. The basic chlorides dehydroxylate, then lose halogen, while the basic bromide loses halogen first and then water. The behaviour of the hydrated fluoride and the basic iodide is complicated by the simultaneous loss of water and halogen as hydrogen fluoride or iodine. Activation energies for some of the reactions have also been derived.
