* Sodium chloride (NaCl) in water: NaCl readily dissolves in water, forming a clear, colorless solution. This is because water is a polar solvent, and NaCl is an ionic compound, meaning it readily dissociates into positively charged sodium ions (Na+) and negatively charged chloride ions (Cl-) in water.

* Sodium chloride in ethanol: Ethanol is also a polar solvent, but less polar than water. While NaCl will dissolve in ethanol to some extent, it will be much less soluble than in water. The solution will appear clear and colorless.

* Sodium chloride in chloroform: Chloroform is a non-polar solvent. NaCl is not soluble in chloroform. You will see two distinct layers: the denser chloroform at the bottom and the NaCl at the top.

Key Takeaway: Sodium chloride is most soluble in polar solvents like water. Its solubility decreases in less polar solvents like ethanol and is practically nonexistent in non-polar solvents like chloroform. The color remains unchanged in all these cases, as NaCl itself is colorless.
