What helps you predict if a compound is soluble or not?

Answer 1

To predict a compound's solubility, consider its molecular structure, including polarity and the presence of functional groups. Generally, polar compounds tend to dissolve in polar solvents (like water), while nonpolar compounds are more soluble in nonpolar solvents. Additionally, the "like dissolves like" principle is useful; for example, ionic compounds often dissolve well in water due to ion-dipole interactions. Finally, factors like temperature and pressure can also influence solubility.
