Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
It is unclear how strong a vacuum Guericke's pump was able to achieve, but if it was able to evacuate all of the air from the inside, the hemispheres would have been held together with a force of around 20 kilonewtons (4,500 lbf; 2.2 short tons-force), [7] [8] equivalent to lifting a car or small elephant; a dramatic demonstration of the ...

Boyle, in this book, became the first to argue that experiment should form the basis of all theory, a common practice in chemistry today. He also expounded on a rudimentary atomic theory and the existence of chemical elements beyond the classic earth, fire, air, and water. [ 5 ]
Chemistry stencils that used to be used for drawing equipment in lab notebooks. A laboratory notebook ( colloq. lab notebook or lab book ) is a primary record of research . Researchers use a lab notebook to document their hypotheses , experiments and initial analysis or interpretation of these experiments.
This is a list of unsolved problems in chemistry. Problems in chemistry are considered unsolved when an expert in the field considers it unsolved or when several experts in the field disagree about a solution to a problem.
“From my standpoint, I think part of why we wanted to make sure we had this opportunity to all be together again — so many of us — right now is that as the holidays come up, and have already ...
The book was also believed to be a source of inspiration to David Hahn, nicknamed "the Radioactive Boy Scout" by the media, who attempted to construct a nuclear reactor in his mother's shed, [2] although the book does not include any nuclear reactions. Due to safety concerns, the book was eventually pulled from library shelves. [3]
