Web23 mei 2012 · 1. The calcium cation is much bigger in size compared to the fluorine anion, hence has less polarising power. The polarisation effects are way much less due to the additional small size (relative) of the fluorine anion (low polarisability). This leads me to conclude that calcium fluoride is highly ionic in nature, and should be soluble in water. Web2 feb. 2024 · Fluorite, CaF 2, is a slightly soluble solid that dissolves according to the equation: CaF 2 ( s) ⇌ Ca 2 + ( a q) + 2 F − ( a q) The concentration of Ca 2+ in a saturated solution of CaF 2 is 2.1 × 10 –4 M; therefore, that of F – is 4.2 × 10 –4 M, that is, twice the concentration of Ca 2 +.
