ebullioscopic造句

• Cryoscopy is related to ebullioscopy, which determines the same value from the ebullioscopic constant ( of boiling point elevation ).
• This improvement made the ebullioscope a standard apparatus to determine the molecular weight of substances in solution by using the ebullioscopic constant of the solvent.
• Among many urban legends related to the effect of ebullioscopic increase, one of them leads to adding salt when cooking pasta only after water has started boiling.
• However, the cryoscopic constant is larger than the ebullioscopic constant and the freezing point is often easier to measure with precision, which means measurements using the freezing point depression are more precise.
• :: There are several tests for functional groups amines, carboxylic acids, ketone, aromatic ring systems make all of them ! . . . . . Than you get the molecular mass by ebullioscopic ( Cryoscopic constant ) best in camphor.
• Here " i " is the van't Hoff factor as above, " K b " is the ebullioscopic constant of the solvent ( equal to 0.512 癈 kg / mol for water ), and " m " is the molality of the solution.
• However, at the approximate concentration of salt in water for cooking ( 10 g of salt per 1 kg of water, or 1 teaspoon per quart ), the ebullioscopic increase is approximately 0.17 癈 ( 0.31 癋 ), which will arguably make no practical difference for cooking, although salt may add to flavors.
