The compound is prepared by treating V 2 O 5 in sulfuric acid with elemental sulfur: [2] V 2 O 5 + S + 3 H 2 SO 4 → V 2 (SO 4) 3 + SO 2 + 3 H 2 O. This transformation is a rare example of a reduction by elemental sulfur. When heated in vacuum at or slightly below 410 °C, it decomposes into vanadyl sulfate (VOSO 4) and SO 2. Vanadium(III ...
H 2 S 2 O 5 +5 (of the sulfur atom bonded to 3 oxygen atoms), +3 (of other sulfur atom) Disulfite commonly known as metabisulfite, S 2 O 2− 5: Not known. Sulfurous acid: H 2 SO 3 +4 Bisulfite, HSO − 3 and sulfite, SO 2− 3: Not known. Dithionous acid: H 2 S 2 O 4 +3 Dithionite, O 2 SSO 2− 2: Not known. Sulfoxylic acid: H 2 SO 2 +2 ...
Electron configuration is also a major factor, illustrated by the fact that the rates of water exchange for [Al(H 2 O) 6] 3+ and [Ir(H 2 O) 6] 3+ differ by a factor of 10 9 also. [4] Water exchange usually follows a dissociative substitution pathway, so the rate constants indicate first order reactions.
Sulfuric(IV) acid (United Kingdom spelling: sulphuric(IV) acid), also known as sulfurous (UK: sulphurous) acid and thionic acid, [citation needed] is the chemical compound with the formula H 2 SO 3. Raman spectra of solutions of sulfur dioxide in water show only signals due to the SO 2 molecule and the bisulfite ion, HSO − 3 . [ 2 ]
Lithium oxide forms along with small amounts of lithium peroxide when lithium metal is burned in the air and combines with oxygen at temperatures above 100 °C: [3] 4Li + O 2 → 2 Li 2 O. Pure Li 2 O can be produced by the thermal decomposition of lithium peroxide, Li 2 O 2, at 450 °C [3] [2] 2 Li 2 O 2 → 2 Li 2 O + O 2
Sodium oxalate starts to decompose above 290 °C into sodium carbonate and carbon monoxide: [2] Na 2 C 2 O 4 → Na 2 CO 3 + CO. When heated at between 200 and 525°C with vanadium pentoxide in a 1:2 molar ratio, the above reaction is suppressed, yielding instead a sodium vanadium oxibronze with release of carbon dioxide [6] x Na 2 C 2 O 4 + 2 ...
It can be prepared by the slow addition of a silver(I) salt to a persulfate solution e.g. AgNO 3 to a Na 2 S 2 O 8 solution. [1] It adopts an unusual structure, being a mixed-valence compound. [2] It is a dark brown solid that decomposes with evolution of O 2 in water. It dissolves in concentrated nitric acid to give brown solutions containing ...
Basic gallium sulfate is known with the formula (H 3 O)Ga 3 (SO 4) 2 (OH) 6. [6] Double gallium sulfates are known with composition NaGa 3 (SO 4) 2 (OH) 6, KGa 3 (SO 4) 2 (OH) 6, RbGa 3 (SO 4) 2 (OH) 6, NH 4 Ga 3 (SO 4) 2 (OH) 6. These compounds are isostructural with jarosite and alunite. Jarosite and alunite can contain a small amount of ...
