Freezing point vs freezing point depression
http://ch302.cm.utexas.edu/physEQ/solution-props/selector.php?name=fp-depression WebThe difference between freezing point osmolality and vapor pressure osmolality (delta osm) is due to the presence of volatiles in the serum, because the volatiles are not measured by vapor pressure osmometry. The amount of ethanol (mg/dL) in serum is estimated by multiplying delta osm by a factor of 4.2.

WebMay 6, 2024 · The freezing point of water becomes lower as more particles are added until the point where the salt stops dissolving. For a solution of table salt ( sodium chloride, NaCl) in water, this temperature is -21 C (-6 F) under controlled lab conditions. In the real world, on a real sidewalk, sodium chloride can melt ice only down to about -9 C (15 F). WebFreezing-point depression is a drop in the minimum temperature at which a substance freezes, caused when a smaller amount of another, non-volatile substance is added. …
