Understanding Solubility
* "Like dissolves like": This principle states that polar solvents dissolve polar solutes, and nonpolar solvents dissolve nonpolar solutes.
Analyzing the Substances
* CCl4 (Carbon Tetrachloride): Nonpolar (symmetrical molecule with no significant dipole moment)
* Br2 (Bromine): Nonpolar (diatomic molecule with no significant dipole moment)
* C6H14 (Hexane): Nonpolar (hydrocarbon with only C-H bonds)
* NaNO3 (Sodium Nitrate): Ionic compound, highly polar
* HCl (Hydrogen Chloride): Polar covalent molecule (due to electronegativity difference between H and Cl)
Solubility in CCl4
Based on the "like dissolves like" principle:
* Soluble:
* CCl4: CCl4 will dissolve in itself (it's a nonpolar solvent).
* Br2: Bromine is nonpolar and will dissolve in CCl4.
* C6H14: Hexane is nonpolar and will dissolve in CCl4.
* Insoluble:
* NaNO3: Sodium nitrate is ionic and highly polar. It won't dissolve in the nonpolar CCl4.
* HCl: Hydrogen chloride is polar and won't dissolve well in the nonpolar CCl4.
Therefore, the following substances will be soluble in carbon tetrachloride (CCl4):
* CCl4
* Br2
* C6H14
