Gadolinium is a chemical element; it has symbol Gd and atomic number 64. Gadolinium is a silvery-white metal when oxidation is removed. It is a malleable and ductile rare-earth element. Gadolinium reacts with atmospheric oxygen or moisture slowly to form a black coating. Gadolinium below its Curie point of 20 °C (68 °F) is ferromagnetic, with ...
Gadolinium (III) chloride, also known as gadolinium trichloride, is GdCl3. It is a colorless, hygroscopic, water-soluble solid. The hexahydrate GdCl 3 ∙6H 2 O is commonly encountered and is sometimes also called gadolinium trichloride. Gd 3+ species are of special interest because the ion has the maximum number of unpaired spins possible, at ...
Gadolinium oxide forms on the surface of gadolinium metal. Gadolinium oxide is a rather basic oxide, indicated by its ready reaction with carbon dioxide to give carbonates. It dissolves readily in the common mineral acids with the complication that the oxalate , fluoride, sulfate and phosphate are very insoluble in water and may coat the grains ...
Gadolinium acetate. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Gadolinium acetate is the acetate salt of the lanthanide element gadolinium, with the chemical formula Gd (CH 3 COO) 3. It is a colorless crystal that is soluble in water and can form a hydrate. [1]
Water is the chemical substance with chemical formula H 2 O; one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom. [25] Water is a tasteless, odorless liquid at ambient temperature and pressure. Liquid water has weak absorption bands at wavelengths of around 750 nm which cause it to appear to have a blue color. [3]
e. The self-ionization of water (also autoionization of water, autoprotolysis of water, autodissociation of water, or simply dissociation of water) is an ionization reaction in pure water or in an aqueous solution, in which a water molecule, H 2 O, deprotonates (loses the nucleus of one of its hydrogen atoms) to become a hydroxide ion, OH −.
Gadolinium (III) nitrate is an inorganic compound of gadolinium. This salt is used as a water-soluble neutron poison in nuclear reactors. [1] Gadolinium nitrate, like all nitrate salts, is an oxidizing agent. The most common form of this substance is hexahydrate Gd (NO 3) 3 •6H 2 O with molecular weight 451.36 g/mol and CAS Number: 19598-90-4.
Water is an inorganic compound with the chemical formula H 2 O.It is a transparent, tasteless, odorless, [c] and nearly colorless chemical substance.It is the main constituent of Earth's hydrosphere and the fluids of all known living organisms (in which it acts as a solvent [19]).
