Alforsite is a barium phosphate chloride mineral with formula: Ba 5 (PO 4) 3 Cl. It was discovered in 1981, and named to honor geologist John T. Alfors (1930–2005) of the California Geological Survey for his work in the area where it was discovered. Alforsite is a hexagonal colorless crystal in the chemical class phosphates and the group apatite.
Barium is a chemical element; it has symbol Ba and atomic number 56. It is the fifth element in group 2 and is a soft, silvery alkaline earth metal . Because of its high chemical reactivity , barium is never found in nature as a free element.
Barium metaphosphate is an inorganic substance with the molecular formula Ba(PO 3) 2. It is a colourless solid that is insoluble in water, though is soluble in acidic solutions through "slow dissolution". [3] X-ray crystallography shows that this material is composed of Ba 2+ cations attached to a polyphosphate ((PO 3 −) n) anion. [4]
The term phosphate is also used in organic chemistry for the functional groups that result when one or more of the hydrogens are replaced by bonds to other groups. These acids, together with their salts and esters , include some of the best-known compounds of phosphorus, of high importance in biochemistry , mineralogy , agriculture , pharmacy ...
In chemistry, a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. It most commonly means orthophosphate, a derivative of orthophosphoric acid, a.k.a. phosphoric acid H 3 PO 4. The phosphate or orthophosphate ion [PO 4] 3− is derived from phosphoric acid by the removal of three protons H +.
Through the same decay mechanism, one decay of barium-130 will occur per second for every 16,000 tons of natural barium, or 27,000 tons of baryte (barium sulfate). [ 33 ] The longest lived isotope of radium is radium-226 with a half-life of 1600 years; it along with radium-223 , -224, and -228 occur naturally in the decay chains of primordial ...
Another way of visualising the structure is that it is the P 4 S 10 adamantane (P 4 O 10) structure with a PS 3+ vertex removed. P 4 S 4− 8 contains a square P 4 ring, [8] P 5 S 5− 10 contains a P 5 ring and P 6 S 6− 12 a P 6 ring. [11] These (PS − 2) n cyclic anions contain P with an oxidation state +3.
Barium acetate is generally produced by the reaction of acetic acid with barium carbonate: [2] BaCO 3 + 2 CH 3 COOH → (CH 3 COO) 2 Ba + CO 2 + H 2 O. The reaction is performed in solution and the barium acetate crystalizes out at temperatures above 41 °C. Between 25 and 40 °C, the monohydrate version crystalizes. Alternatively, barium ...
