Its simply the equilibrium constant (Keq) for an ionic substance dissolving in water. However, compounds that we know to be highly soluble, like salt, are likely to form solutions at various ratios; in this case, we will be able to determine how much solute and solvent is needed to form each solution, and if it's possible to form one at all. Most silver salts are insoluble. A solute is considered insoluble when they are unable to dissolve at a ratio greater than 10000:1. Thanks for contributing an answer to Chemistry Stack Exchange! The refractive index is about 1.46 from 700nm to 5m.[11]. However, with fluorides and hydroxides the lattice energy decreases more rapidly than the hydration energy, and so their solubility increases on descending the group.

Luckily, solubility follows a list of rules that helps us determine how soluble a substance is, like how likely that salt is to dissolve into that water (sneak peek- its very likely). Compare the solubility in this case with that of BaF 2 in pure water. A compound's molar solubility in water can be calculated from its K value at 25C. In general, the solubility of a substance depends on not only the energetic factors we have discussed but also the temperature and, for gases, the pressure. 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. However, the process of solubility is unique, and the rate at which it dissolves is not factored into the equation. Important exceptions to this rule include CaSO4, BaSO4, PbSO4, Ag2SO4 and SrSO4 .

The solubility of a substance fundamentally depends on the physical and chemical properties of the solute and solvent as well as on temperature, pressure and the pH of the solution. When a solute is mixed with a solvent, there are three possible outcomes: If the solution has less solute than the maximum amount it is able to dissolve (the solubility), it is a dilute solution. One of our academic counsellors will contact you within 1 working day. The multiplication of ions of a specific compound when particularly dissolved in an aqueous solution becomes equivalent to solubility product.
