In a binary liquid system, the composition expressed as _______________ is independent of the temperature & pressure?
Correct answer: D. All A., B. & C.
- A. Kg of solute/kg of solvent
- B. Kg-mole of solute/kg-mole of solvent
- C. Kg-mole of solute/1000 kg of solvent
- D. All A., B. & C.
Explanation
Ratios based on amounts of solute and solvent, such as kg/kg, kg-mol/kg-mol, and kg-mol per 1000 kg solvent, do not change with temperature or pressure. Hence all three listed composition forms are independent of T and P.
