• Online Middle School Chemistry Resource

    Updated: 2024-02-29 20:18:54
    The ACS Education Division has developed a new middle school chemistry resource, "Middle School Chemistry: Big Ideas about the Very Small." This free, six-chapter resource can serve as either a stand-alone chemistry unit or as a supplement to any middle school science curriculum. "Middle School Chemistry" uses a hands-on inquiry approach along with specially designed molecular model animations, to take students from concrete experiences to an understanding of the world of atoms and molecules. Share this free resource with middle school teachers you know.

    Nitric acid is effective since it is also a potential oxidant. Its use is standard in acid digestion of organic material. Aqua regia contains nitric acid, so yes it will also work to digest organic matter, although it is more dangerous to handle and brings nothing else to the table if all you want to do is eliminate the organic material. Its use in digestions is motivated by the fact that chloride can act as a stabilizing element for extraction of heavy metals prior to trace metal analysis.If all you want to do is digest polymer, pure nitric acid is a better choice IMO. Going back to the original question, though, neither nitric acid or AR will be very effective against the silicate fiber component of fiberglass.

    I preferre wet-loading, if your sample does not dissolve in the eluent you should change it, for example use toluene instead of hexane. I think generally you get a more narrow band of the sample if you use wet-load and thus better separation. I have never tried dry-loading a RP column.
