WebSolution. According to the stoichiometry of the dissolution equation, the fluoride ion molarity of a CaF 2 solution is equal to twice its calcium ion molarity: [F −] = (2molF − /1molCa2 +) = (2)(2.15 × 10 − 4M) = 4.30 × 10 − 4M. Substituting the ion concentrations into the Ksp expression gives.
At temperatures around 600 °C, calcium cyanide converts to calcium cyanamide: Ca(CN)2 → CaCN2 + C It is suspected that this reaction is one step in the conversion of calcium carbide with nitrogen gas. The ratio of calcium cyanide to calcium cyanamide is sensitive to the presence of alkali metal halides, such as sodium chloride.
