As for any solution, the solubility of a gas in a liquid is affected by the attractive intermolecular forces between solute ...
용액 농도를 표현하는 방법
A solute is a component of a solution that is typically present at a much lower concentration than the solvent. Solute concentrations are often described ...
증기 압력 내림
The equilibrium vapor pressure of a liquid is the pressure exerted by its gaseous phase when vaporization and condensation are occurring at equal rates:
...
이상용액
According to Raoult’s law, the partial vapor pressure of a solvent in a solution is equal or identical to the vapor pressure of the pure solvent ...
어는점 내림과 끓는점 오름
Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the ...
삼투와 용액의 삼투압
A number of natural and synthetic materials exhibit selective permeation, meaning that only molecules or ions of a certain size, shape, polarity, charge, ...
