Figure 5.1. 2: As potassium chloride (KCl) dissolves in water, the ions are hydrated. The polar water molecules are attracted by the charges on the K + and Cl − ions. Water molecules in front of and behind the ions are not shown. 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. biosecurity dairy farms

Web8 mei 2010 · The question asks in what solution will CaF2 be least soluble? So the least soluble solution is one that already has some Ca or some F in it. The equation is CaF2 -> Ca^2+ + 2F^-. So Ksp = (Ca^2+)* (F^-)^2. Notice F- is squared so it has a higher impact. Choice 5 has none of them so CaF2 will dissociate in it the best.
