The United States National Chemistry Olympiad (or USNCO) is a contest held by the American Chemical Society (ACS) used to select the four-student team that represents the United States at the International Chemistry Olympiad (IChO). Each local ACS section selects 10 students (or more for larger ACS sections) to take the USNCO National Exam. To ...
In 1874, a group of American chemists gathered at the Joseph Priestley House to mark the 100th anniversary of Priestley's discovery of oxygen.Although there was an American scientific society at that time (the American Association for the Advancement of Science, founded in 1848), the growth of chemistry in the U.S. prompted those assembled to consider founding a new society that would focus ...
ACS grade is the highest level of purity, and meets the standards set by the American Chemical Society (ACS). The official descriptions of the ACS levels of purity is documented in the Reagent Chemicals publication, issued by the ACS. [3] [4] It is suitable for food and laboratory uses. Reagent grade is almost as stringent as the ACS grade.
Reagent Chemicals [a] is a publication of the American Chemical Society (ACS) Committee on Analytical Reagents, [1] detailing standards of purity for over four hundred of the most widely used chemicals in laboratory analyses and chemical research. Chemicals that meet this standard may be sold as "ACS Reagent Grade" materials.
The ACS Style is a set of standards for writing documents relating to chemistry, including a standard method of citation in academic publications, developed by the American Chemical Society (ACS).
The journal has absorbed two other publications in its history, the Journal of Analytical and Applied Chemistry (July 1893) and the American Chemical Journal (January 1914).

The Journal of Physical Chemistry B is a peer-reviewed scientific journal that covers research on several fields of material chemistry (macromolecules, soft matter, and surfactants) as well as statistical mechanics, thermodynamics, and biophysical chemistry. It has been published weekly since 1997 by the American Chemical Society.
The 2014 AP Chemistry exam was the first administration of a redesigned test as a result of a redesigning of the AP Chemistry course. The exam format is now different from the previous years, with 60 multiple choice questions (now with only four answer choices per question), 3 long free response questions, and 4 short free response questions ...
