This system exhibits the phenomenon of 2 boiling points at atmospheric pressure, namely at 140.9° C and at 176.1° C. Neither the presence of 2 stable maxima, nor the occurrence of 2 boiling points (at 1 at) had till now ever been observed in solutions saturated with two salts.doi:...
The vapour pressure of solutions of carbon dioxide in Freon has been determined at 10° and 20 °C. for pressures up to 25 atm. At both temperatures, the vapour pressure is roughly linear in the mole fraction of carbon dioxide, the deviations being positive for solutions low in carbon ...

The most accurate observations are made when we observe the light emitted when the vapour pressure is low.───当蒸气压很低时,可以对原子所发射的光谱作出最精确的观测。 英语使用场景 An expression for the lowering of vapour pressure for dilute solutions can be derived from Raoult's law. Figure...
Vapour pressure is a colligative property of solutions. The vapour pressure of a solution is always lower than the vapour pressure of the pure solvent. Ratio of solution to pure solvent vapour pressures is approximately equal to the mole fraction of solvent in the solution. Citing this page: Ge...
Raoult’s Law relates the vapour pressure of the solvent above the solution to its mole fraction in the solution. Which of the following is an accurate statement?A.Raoult’s Law applies exactly to all solutions.B.Raoult’s Law works best when applied to
