The substance that is dissolved is called a solute, and the substance it is dissolving in is called a solvent. Solution The key to solving solubility problems is to properly set up your dissociation reactionsand define solubility. Sodium chloride contains Na, which is almost always soluble according to rule 1, and Cl, which is usually soluble according to rule 3. The rate of solution refers to how quickly a substance dissolves, and is separate from solubility. [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].

Calculate the solubility product, Ksp, of both compounds. With most compounds, on descending the group, the hydration energy decreases more rapidly than the lattice energy: hence the compounds become less soluble as the metal gets larger. Previous question Next question. Sorry i interpreted the question wrong BaF2 is more soluble than BeF2 because for molecules having small anions like flouride , oxide ,hydroxides etc solubility increases down the group because lattice energy decreases .If you fund it useful please approve it. While we can calculate the solubility by measuring each substance and following an equation, the solubility rules allow us to determine the solubility of a substance before you attempt to create it. As we see from our solubility rules, some substances are very soluble, while some are insoluble or have low solubility. For example, sugar is a polar solute, and absorbs very well in water. You will see in the solubility rules that many compounds that are labeled as insoluble have exceptions, such as carbonates. What is the molar solubility of barium fluoride (BaF2) in water? Using mole ratios, the [Ag+] will go up by (2 x 1.31 x 10-4 moles/L) = 2.62 x 10-4 moles/L.
