  • What is the cause of hygroscopy? - Chemistry Stack Exchange
    Ions are hygroscopic because they form very stable, low energy hydrates, which are thermodynamically favorable over water vapor I E salt attracts water vapor because the hydrated salt is lower energy than the water vapor Other very porous materials are hygrosopic due to capillary action
  • Hygroscopic Substances and Drying Agents - Chemistry Stack Exchange
    all drying agents are hygroscopic substances First Terminology: Hygroscopic: Absorbs water from air Drying agent: Removes water from organic substance Your book did not exclude other materials from being considered drying agents It just said many of the substances that are hygroscopic are also useful as drying agents
  • hygroscopicity vs solubility - Chemistry Stack Exchange
    Phenols are hygroscopic and form a red liquid, upon contact with air Yet, Phenol’s solubility in water is said to be moderate ( Tilted to the low solubility side) This is explained with the benzene ring being non polar Then how can it be hygroscopic? Are solubility and hygroscopicity even related at all, then?
  • reaction mechanism - What makes these particles hygroscopic . . .
    The composition of petrol diesel is very different, that's why it is not as hygroscopic as biodiesel As far as I know hygroscopy depends mostly on polarity The water molecule is a polar, so it likes to mix with other polar compounds, like KOH, glycerol, salt, sugar, H2SO4, etc Apolar compounds repel water
  • water - If polyethylene glycol (PEG) is hygroscopic, how does it . . .
    Coming to your point on the hygroscopic property (also known as deliquescence) Higher molecular weight PEG has lower hygroscopic property because of more alkyl chained part So it depends on the type of PEG used But a balance has to be made since, lower MW chains are easier to penetrate tissue
  • Is an aqueous solution of calcium chloride hygroscopic?
    Sulfuric acid is hygroscopic, even if not anhydrous So a solution containing water can be hygroscopic Is a concentrated solution of calcium chloride that was created by the solid salt attracting water still hygroscopic, attracting more water? If yes - down to which concentration is that the case?
  • water - Does storing a hygroscopic reagent in a bottle makes it prone . . .
    Does storing a hygroscopic reagent in a bottle makes it prone to absorb humidity from the air trapped inside? Yes, there is that tendency I'll make a couple of points which I'll number for possible further discussion (1) 99 5% acetone is probably 0 5% water
  • Is 70% ethanol hygroscopic? - Chemistry Stack Exchange
    85% ethanol made with nuclease free water (Note: 85% ethanol is hygroscopic Fresh 85% ethanol should be prepared for optimal results) I know that this is even more pronounced for 100% ethanol But I'm wondering if 70% is still "very" hygroscopic so that the concentration might change over time
  • everyday chemistry - Is there a point at which Ethanol (E10) fuel . . .
    In addition, sulfuric acid is even more hygroscopic than ethanol; at concentrations in water as low as 10%, it'll attract more water Lastly, acids and alcohols form esters, in our case ethyl sulfate, and esters and alcohols form ethers, here diethyl ether (with the sulfuric acid and water as a byproduct)
  • Hygroscopic behaviour of DMSO - Chemistry Stack Exchange
    In the MSDS of DMSO I find that the liquid is hygroscopic, meaning it adsorbs moisture from the surrounding environment Unfortunately, I cannot find anywhere how much water will be absorbed (mass%) or how quickly this will happen, is it saturated in minutes, hours, days?
