Soluble

Definition

Soluble substances are those that can dissolve in a solvent, forming a homogeneous mixture at the molecular or ionic level. Solubility is essential in predicting the outcomes of chemical reactions.

5 Must Know Facts For Your Next Test

1. Solubility depends on temperature; for many solids, solubility increases with temperature.
2. Polar solvents like water dissolve polar solutes and ionic compounds due to their ability to stabilize ions.
3. Nonpolar solvents dissolve nonpolar solutes because of similar intermolecular forces.
4. The solubility product constant ($$K_{sp}$$) indicates the extent to which a compound will dissolve in water.
5. In stoichiometry, soluble compounds dissociate completely into their constituent ions in solution.
