Explainer: Why is mixing cleaning chemicals such a bad idea?
WEBApr 23, 2020 · Chlorine gas is toxic, forms acids on contact with wet surfaces, such as home plumbing but also living tissue, such as the lungs. Heating or contact with metals can also cause bleach to decompose via a different route. 2NaOCl → O 2 + 2NaCl. Mixing hypochlorite with ammonia would see the breakdown of the hypochlorite to generate hypochlorous ...

The father of the periodic table | Feature | Chemistry World
WEBJan 2, 2019 · A century and a half ago, Dmitri Mendeleev took a crucial step in this search for order among the elements, by publishing the first draft of his periodic table. In 2019 the world-wide community of chemists is celebrating this anniversary, and rightly so. Like Stonehenge, the table reflects regularities in nature which were due to causes that ...
Explainer: The chemistry that keeps swimming pools clean and safe
WEBAug 4, 2022 · Chloramines can form in various ways in swimming pools. One of the simplest is the reaction of ammonia-like compounds, such as urea from swimmers, with hypochlorous acid. This leads to the formation of mono-, di- and trichloramines. Chloramine formation: R 2 NH + HOCl → R 2 NCl + H 2 O. These toxic chloramines then evaporate, producing the ...

Ink chemistry | News | Chemistry World
WEBFeb 28, 2003 · Ink chemistry. There are probably as many different definitions of ink as there are types. Perhaps the simplest description is that ink is a liquid or semi-liquid material used for writing, printing or drawing. Chemists view it as a colloidal system of fine pigment particles dispersed in a solvent (Chem. Br., February 2003, p28).
What it takes to make a new element | Feature | Chemistry World
WEBNov 30, 2016 · Results of fusion reactions were decreasing sharply as the atomic number grew higher. The cause was the high excitation energy (40–50MeV), which increased the chance of the element breaking up. To create new elements, the excitation energy needed to be minimal, or ‘cold’.
ChemSpider | Review | Chemistry World
WEBOct 2, 2009 · ChemSpider is a chemistry search engine, aggregating and indexing chemical structures and their associated information into a single searchable repository, and free at that. In my experience it has always been more than a chemistry database (taking in over 21 million molecules, including drugs and drug-like structures).
