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 ...
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 ...
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 ...
2 NH 3 + SO 2 + H 2 O → (NH 4) 2 SO 3. Ammonium sulfite is produced in gas scrubbers, now obsolete, consisting of ammonium hydroxide to remove sulfur dioxide from emissions from power plants. The conversion is the basis of the Walther Process. The resulting ammonium sulfite can be air oxidized to give ammonium sulfate. [4]
There are several general reasons for this: (1) they may condense to form oligomers (e.g., H 2 CrO 4 to H 2 Cr 2 O 7), or dehydrate all the way to form the anhydride (e.g., H 2 CO 3 to CO 2), (2) they may disproportionate to one compound of higher and another of lower oxidation state (e.g., HClO 2 to HClO and HClO 3), or (3) they might exist ...
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 ...
Co + H 2 SO 4 + 7 H 2 O → CoSO 4 (H 2 O) 7 + H 2 CoO + H 2 SO 4 + 6 H 2 O → CoSO 4 (H 2 O) 7. The heptahydrate is only stable at humidity >70% at room temperature, otherwise it converts to the hexahydrate. [2] The hexahydrate converts to the monohydrate and the anhydrous forms at 100 and 250 °C, respectively. [1] CoSO 4 (H 2 O) 7 → CoSO ...
Bismuth(III) sulfate is an inorganic chemical compound of bismuth with the formula Bi 2 (SO 4) 3. It is a hygroscopic white solid that decomposes at 465 °C to bismuth(III) oxysulfate and is isotypic to antimony(III) sulfate .
