dry chlorine passed over heated aluminium foil

CHEMICAL REACTIONS OF THE PERIOD 3 ELEMENTS - chemguide

Aluminium is often reacted with chlorine by passing dry chlorine over aluminium foil heated in a long tube. The aluminium burns in the stream of chlorine to produce very pale yellow aluminium chloride. This sublimes (turns straight from solid to vapour and back again) and collects further down the tube where it is cooler.

Why is Iron (II) Chloride not formed when chlorine gas is

Chlorine is a powerful oxidising agent so while iron(II) may initially form, it will go on to produce iron(III). To prepare a sample of hydrated iron(II) choride you could react iron(II) oxide or carbonate with XS dilute HCl, filter and crystallise. 2.1k views · View 4 Upvoters
