Why does Sodium Fluoride NaF have a high melting point
Oct 27, 2011· Why does Sodium Fluoride NaF have a high melting point/boiling point? I was wondering why NaF has such a high MP/BP, with a MP of 993°C and a BP of 1695°C I'm supposed to compare salts with each other. Another salt that I have is Ammonium Nitrate (NH4NO3) which has a MP of 170°C and a BP of 210°C.

why do CaCl2 have a greater affect on the freezing point
Apr 26, 2011· Sodium Chloride, (NaCl) has only two ions. Calcium chloride, (CaCl2) has three ions. More ions = higher melting point and lower freezing point. Calcium chloride doesn''t melt ice and snows on roads, it simply prevents them from freezing over via lowering the freezing point.
