Sodium chloride contains Na, which is almost always soluble according to rule 1, and Cl, which is usually soluble according to rule 3. Solution The key to solving solubility problems is to properly set up your dissociation reactionsand define solubility. The dissociation reaction of compound BaF 2 in water is: BaF2(s) Ba+ (aq) + 2 F- (aq) This reaction shows that for every single mole of BaF 2 that dissolves, 1 mole of Ba+ and 2 moles of F- are formed as a result. [14] Another proposal is that polarisation of the electron core of the barium atom creates an approximately tetrahedral distribution of charge that interacts with the Ba-F bonds.[15].
