Borax - Encyclopedia

Borax crystallizes with ten molecules of water, the composition of the crystals being Na2B407+10H20. The crystals belong to the monoclinic system, and it is a curious fact that in habit and angles they closely resele pyroxene (a silie of calcium, magnesium and iron).

calcium carbonate calcite

Calcium carbonate is a chemical compound, with the chemical formula Ca C O 3. The elements involved are calcium (Ca), carbon (C) and oxygen (O). It is a common substance found as rock in all parts of the world, and is the main component of seashells

Sodium carbonate | Sustainable Community Action | …

Sodium carbonate (also known as washing soda, soda ash and soda crystals), Na2CO3, is the sodium salt of carbonic acid (soluble in water). It most commonly occurs as a crystalline heptahydrate, which readily effloresces to form a white powder, the monohydrate. Pure sodium carbonate is a white, odourless powder that is hygroscopic (absorbs moisture from the air), has an alkaline taste, and


B2O3⋅5 H2O. Boric acid (H 3BO 3) is produced in Turkey and Europe mainly by the reaction of colemanite with sulfuric acid. The reaction is carried out at temperatures above 80 C. Calcium sulfate dihydrate (gypsum, CaSO 4·2 H2O) crystallizes from the

Han purple is an artificial pigment created by the Chinese over 2,500 years ago, which was used in wall paintings and to decorate the famous terracotta warriors, as well as ceramics, metal ware, and jewelry. The pigment is a technological wonder, made through a

Gemstone Info | 1001 Rare Gemstones

Thomsonite Belonging to the zeolite family of minerals, thomsonite is a hydrated calcium sodium aluminium silie – (Ca, Na2) Al2Si2O8.H2O – which crystallizes in the orthorhoic system. The gem material is mostly columnar with a radial structure, or as radiated spherical aggregates or concretions, which are translucent and closely resele agate.

Borax - CreationWiki, the encyclopedia of creation science

Borax is found in playa lakes and evaporated deposits. Playas are arid regions where the evaporation of water causes the formation of lakes to be sporadic throughout the year. They form from the runoff water coming down from the neighboring mountains during the …

Like barium and the alkali metals, radium crystallizes in the body-centered cubic structure at standard temperature and pressure: the radium–radium bond distance is 514.8 picometers. Radium has a density of 5.5 g/cm3, higher than that of barium, again confirming periodic trends; the radium-barium density ratio is comparable to the radium-barium atomic mass ratio, due to the two elements

apart. It fails if other ions are present, because most metal carbonates are insoluble and will precipitate. In addition, calcium, zinc, and lead ions all produce white precipitates with carbonate, making it difficult to distinguish between them. Instead
