Compounds Of Alkaline Earth Metals - Study Material for …
Calcium fluoride or fluorospar (CaF 2) is by far the most important of all the fluorides of the alkaline earth metals since it is the only large scale source of fluorine. CaCl 2 is widely used for melting ice on roads, particularly in very cold countries because 30% eutectic mixture of CaCl2/ice freezes at 218 K as compared to NaCl /ice at 255K.
Fluoride - Wikipedia
Fluoride is the simplest fluorine anion. In terms of charge and size, the fluoride ion reseles the hydroxide ion. Fluoride ions occur on earth in several minerals, particularly fluorite, but are present only in trace quantities in bodies of water in nature.
