Chemistry

Solubility is all about whether a substance's particles can be pulled apart and surrounded by water molecules. The key is recognizing common patterns: most salts dissolve (especially those with $\text{Na}^+$, $\text{K}^+$, or $\text{NO}_3^-$), while hydroxides and carbonates are often insoluble unless paired with those same "friendly" cations. Think about what happens at the molecular level—can water's polar nature break apart the ionic bonds or interact with the substance?
