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 ...
Ammonium hexachloroplatinate is used in platinum plating. Heating (NH 4) 2 [PtCl 6] under a stream of hydrogen at 200 °C produces platinum sponge. Treating this with chlorine gives H 2 [PtCl 6]. [2] Ammonium hexachloroplatinate decomposes to yield platinum sponge when heated to high temperatures: [2] [5] 3(NH 4) 2 PtCl 6 → 3Pt(s) + 2NH 4 Cl ...
Description: This book explained Dalton's theory of atoms and its applications to chemistry. Importance: The book was one of the first to describe a modern atomic theory, a theory that lies at the basis of modern chemistry. [3]: 251 It is the first to introduce a table of atomic and molecular weights.
By 1917, they sold chemistry sets, which they produced through World War II, in spite of restrictions on materials. Robert Treat Johnson, noting the number of chemistry students at Yale whose interest in the science began with a chemistry set, argued the production of chemistry sets was a "patriotic duty." [5]

The Raw Materials. A burger is as good as its patty, and frozen beef is a one-way ticket to flavorless disappointment. Ice crystals that form during freezing can affect the meat’s texture and ...
