A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
A selection of chemicals included in the chemistry set "Chemistry 4" from Salter Science. Some of the chemistry sets produced by Salter Science contained this tube of Patent Blue V, under the name of "Sky Blue". The dye colors water blue, but turns green in acidic solutions.
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 ...
A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction.

Coire nan Lochan, a corrie of Bidean nam Bian on the southern side of Glen Coe Glencoe by Hugh William Williams, c. 1825–1829. The glen is U-shaped, formed by an ice age glacier, [9] about 12.5 kilometres (7 + 3 ⁄ 4 mi) long with the floor of the glen being less than 700 metres (3 ⁄ 8 mi) wide, narrowing sharply at the "Pass of Glen Coe".
Barrow County Superior Court Judge Nicholas Primm set bond at $500,000 on Tuesday for Gray, 54, whose 14-year-old son Colt Gray is accused of going into Alapachee High School and opening fire with ...
Contributing structures of the carbonate ion. In chemistry, resonance, also called mesomerism, is a way of describing bonding in certain molecules or polyatomic ions by the combination of several contributing structures (or forms, [1] also variously known as resonance structures or canonical structures) into a resonance hybrid (or hybrid structure) in valence bond theory.
Nuclear chemistry is the sub-field of chemistry dealing with radioactivity, nuclear processes, and transformations in the nuclei of atoms, such as nuclear transmutation and nuclear properties. It is the chemistry of radioactive elements such as the actinides , radium and radon together with the chemistry associated with equipment (such as ...
