  • 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 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
  • 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?
  • 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 So the "extra" water from the air above the acetone in the bottle (from one opening and closing of the cap) would be negligible
  • Is 70% ethanol hygroscopic? - Chemistry Stack Exchange
    70% is still "very" hygroscopic so that the concentration might change over time Say differently, how stable is the ethanol concentration over time? How long would a 70% ethanol solution last? That may depend on the volume made, but I want to know if there could be a "best before" date so that it's no longer considered as a 70% ethanol solution
  • 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
  • Does urine make concrete hygroscopic? - Chemistry Stack Exchange
    TLDR: Does urine make concrete hygroscopic enough to absorb moisture from the air so much that a spot of humidity is visible? Are uric acid crystals moisture-absorbent? (Urea apparently is accordin
