  2. Isopropyl alcohol - Wikipedia

    en.wikipedia.org/wiki/Isopropyl_alcohol

    Isopropyl alcohol (IUPAC name propan-2-ol and also called isopropanol or 2-propanol) is a colorless, flammable, organic compound with a pungent alcoholic odor. [9]Isopropyl alcohol, an organic polar molecule, is miscible in water, ethanol, and chloroform, demonstrating its ability to dissolve a wide range of substances including ethyl cellulose, polyvinyl butyral, oils, alkaloids, and natural ...

  3. Cooling bath - Wikipedia

    en.wikipedia.org/wiki/Cooling_bath

    Both flasks are submerged in a dry ice/acetone cooling bath (−78 °C) the temperature of which is being monitored by a thermocouple (the wire on the left). A cooling bath or ice bath , in laboratory chemistry practice, is a liquid mixture which is used to maintain low temperatures, typically between 13 °C and −196 °C.

  5. The Easy Way to Melt Ice You Never Knew About (It’s Not Salt!)

    www.aol.com/easy-way-melt-ice-never-210537871.html

    Turns out, rubbing alcohol has a much lower freezing point than water (128°F below 0), so it speeds up the melting process and prevents the surface from icing up in the future, Rossen says.

  6. Ice protection system - Wikipedia

    en.wikipedia.org/wiki/Ice_protection_system

    Sometimes called a weeping wing, [6] running wet, or evaporative system, these systems use a deicing fluid, typically based on ethylene glycol or isopropyl alcohol, to prevent ice forming and to break up accumulated ice on critical surfaces of an aircraft. [7]

  7. Why salt melts ice — and how to use it on your sidewalk - AOL

    A chemistry professor explains the science that makes salt a cheap and efficient way to lower freezing temperature.

  8. Will Using Rock Salt For Ice Kill Your Grass? - AOL

    www.aol.com/using-rock-salt-ice-kill-040000219.html

    A generous sprinkle of rock salt on sidewalks, driveways, roads, and bridges melts ice away by lowering the freezing point of water. A thin layer of water forms, causing the ice to break up.
