The solvent or mixture of solvents used for separation of compounds is called____________________?
Correct answer: B. Mobile phase
- A. Stationary phase
- B. Mobile phase
- C. Dynamic phase
- D. Static phase
Explanation
In chromatography, the solvent or solvent mixture that moves through the system and carries the sample is the mobile phase. The stationary phase remains fixed and interacts differently with each component, causing separation. Students may choose a by remembering that the sample contacts the stationary phase, but the moving solvent is specifically the mobile phase.

About Properties of Liquids
Liquid behavior depends on intermolecular forces, which produce surface tension, viscosity, capillary action and a definite volume without a fixed shape. The topic also covers vapor pressure, evaporation, boiling point and the effect of temperature and external pressure, while distinguishing evaporation at the surface from boiling throughout the liquid.
