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. Solution The key to solving solubility problems is to properly set up your dissociation reactionsand define solubility. To do so, first prepare an ICE (Initial, Change, and Equilibrium) table showing the equilibrium concentrations of the ions in terms of x, the molar solubility of the compound.Then, plug these expressions into the solubility-product expression for the compound and solve for the value of x. Knowing and following the solubility rules is the best way to predict the outcome of any given solution. Rate should not be factored into the solubility of a substance.This can often be confusing when first learning about solubility, since in a visual example, watching something dissolve quickly can feel like an affirmation of its ability to dissolve. When you are working on chemical equations or building a hypothesis, solubility rules are helpful in predicting the end states of the substances involved.
