•  Salt (chemistry)

  In chemistry, salts are ionic compounds which can result from the neutralization reaction of acids. Salts are ionic compounds composed of cations and anions (negative ions) so that the product is electrically neutral (without a net charge). These component ions can be inorganic such as chloride (Cl), as well as organic such as acetate (CH3COO) and monoatomic ions such as fluoride (F), as well as polyatomic ions such as sulfate (SO4). There are several varieties of salts.

•  Sulfuric acid

  Sulfuric acid (sulphuric acid in British English) is a strong mineral acid with the molecular formula H2SO4. It is soluble in water at all concentrations. Sulfuric acid has many applications, and is one of the top products of the chemical industry. World production in 2001 was 165 million tonnes, with an approximate value of US$8 billion.

•  Pyrite

  The mineral pyrite, or iron pyrite, is an iron sulfide with the formula FeS2. This mineral's metallic luster and pale-to-normal, brass-yellow hue have earned it the nickname fool's gold due to its resemblance to gold. The color has also led to the nicknames brass, brazzle and brazil, primarily used to refer to pyrite found in coal. Pyrite is the most common of the sulfide minerals. The name pyrite is derived from the Greek πυρίτης (puritēs), “of fire” or "in fire”, from πύρ (pur), “fire”.

•  Cinnabar

  Cinnabar,, is the common ore of mercury. The name comes from κινναβαρι (kinnabari), a Greek word most likely applied by Theophrastus to several distinct substances. Other sources say the word comes from the Persian زینجیفرح zinjifrah, a word of uncertain origin. In Latin it was sometimes known as minium, meaning also "red lead", though both of these terms now refer uniquely to lead tetroxide.

•  Aqua regia

  Aqua regia or aqua regis (Latin for royal water or king's water) is a highly corrosive, fuming yellow or red solution, also called nitro-hydrochloric acid. The mixture is formed by freshly mixing concentrated nitric acid and concentrated hydrochloric acid, usually in a volumetric ratio of 1:3 respectively. It was named so because it can dissolve the so-called "royal metals," or noble metals, gold and platinum.

•  Natron

  Natron is a naturally occurring mixture of sodium carbonate decahydrate and about 17% sodium bicarbonate along with small quantities of household salt and sodium sulfate. Natron is white to colourless when pure, varying to gray or yellow with impurities. Natron deposits are sometimes found in saline lake beds which arose in arid environments. Throughout history natron has had many practical applications which still resonate in the wide range of modern uses of its constituent mineral components.

•  Calcium oxide

  Calcium oxide (CaO), commonly known as quicklime, is a widely used chemical compound. It is a white, caustic and alkaline crystalline solid at room temperature. As a commercial product, lime often also contains magnesium oxide, silicon oxide and smaller amounts of aluminium oxide and iron oxide. Calcium oxide is usually made by the thermal decomposition of materials such as limestone, that contain calcium carbonate in a lime kiln.

•  Philosopher's stone

  The philosophers' stone is a legendary alchemical substance, supposedly capable of turning base metals, especially lead, into gold; it was also sometimes believed to be an elixir of life, useful for rejuvenation and possibly for achieving immortality. For a long time, it was the most sought-after goal in Western alchemy, meditated upon by alchemists like Sir Isaac Newton, Nicolas Flamel, and Frater Albertus.

•  Silver nitrate

  Silver nitrate is an inorganic compound with chemical formula AgNO3. This compound is a versatile precursor to many other silver compounds, such as those used in photography. It is far less sensitive to light than the halides. It was once called "lunar caustic" because silver was called luna by the ancient alchemists. In solid silver nitrate, the silver ions are three-coordinated in a trigonal planar arrangement.
