I transcribed for you this time but might be less generous in the future. 7 10 - 6 at 25C. However, with fluorides and hydroxides the lattice energy decreases more rapidly than the hydration energy, and so their solubility increases on descending the group. However, solutes can be in any state: gas, liquid, or solid. If there is more solute than is able to be dissolved, the excess separates from the solution and forms a precipitate. Strong and can be used in high pressure applications 3. Question 19 Which of the following substances has the greatest solubility in water?
