Chemical Formula: ... Methyl chloroform: 71-55-6: 1000 pounds: X: U226 WebThe boiling point of chloroform at 80 kPa is roughly 53 Celsius degrees. Why does the boiling point of a liquid vary depending on the atmospheric pressure? Atmospheric pressure is usually what we understand for external pressure, and it is the total pressure of all the gases in the air. Explain how evaporation lowers the temperature of a liquid.

WebMar 1, 2024 · Owing to its high vapor pressure and Henry's law constant, chloroform released to surface soil or water has the potential to escape to the atmosphere. It adsorbs poorly on soil particles, particularly on soils with low organic matter, due to its low octanol–water partition coefficient, leading to leaching into groundwater (Howard, 1991 ). WebBoiling point and vapor pressure are inversely related. A higher vapor pressure creates a lower boiling point. (When the vapor pressure equals atmospheric pressure, the solvent is boiling.) Since the azeotrope has the lowest boiling point possible in a mixture, it has the highest vapor pressure. Therefore, the azeotrope evaporates out of a solution
