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.
