  • What is the cause of hygroscopy? - Chemistry Stack Exchange
    Hygroscopy is the ability of a substance to attract and hold water molecules from the surrounding environment Why are some compounds hygroscopic and others are not? What is it about their struct
  • 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?
  • Hygroscopic Substances and Drying Agents - Chemistry Stack Exchange
    It just said many of the substances that are hygroscopic are also useful as drying agents Take for example anhydrous calcium chloride calcium sulfate hemihydrate (also called plaster or Drierite TM) and phosphorous pentoxide
  • 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?
  • Storage of air and temperature sensitive reagents [closed]
    For some hygroscopic compounds, also additional heating might be necessary in combination with high vacuum to get it really dry If your compound can be easily evaporated, and has a boiling point significantly different from water, destillation in a previously dried apparatus might be an option
  • How can I store reagent under inert gas? - Chemistry Stack Exchange
    It depends on how carefully it is done And depending on the way you close the vial, the cap, etc I can't write an answer for this But consider asking a colleague to be there for quick action Longer you bubble better it is Ar is better than N2 Etc Or a vacuum inert line is on place and a branch of it is for storage For prolonged storage or relatively small sample vials of thin glass
  • experimental chemistry - What are some ways of storing some chemicals . . .
    I will order a reagent that is hydroscopic and recommended to be stored under inert gas I suppose something like a glovebox is best but I would like to exploe some alternative options that are a bit
  • reaction mechanism - What makes these particles hygroscopic . . .
    Hygroscopy is the ability of a substance to attract and hold water molecules from the surrounding environment For cotton there is capillary action Hydrates like KOH attract water due to lower en
