CoSO 4 (H 2 O) 7 → CoSO 4 (H 2 O) 6 + H 2 O CoSO 4 (H 2 O) 6 → CoSO 4 (H 2 O) + 5 H 2 O CoSO 4 (H 2 O) → CoSO 4 + H 2 O. The hexahydrate is a metal aquo complex consisting of octahedral [Co(H 2 O) 6] 2+ ions associated with sulfate anions (see image in table). [3] The monoclinic heptahydrate has also been characterized by X-ray ...
Phosphomolybdic acid – H 3 PMo 12 O 40; Phosphoric acid – H 3 PO 4; Phosphorous acid (Phosphoric(III) acid) – H 3 PO 3; Phosphoroyl nitride – NPO; Phosphorus pentabromide – PBr 5; Phosphorus pentafluoride – PF 5; Phosphorus pentasulfide – P 4 S 10; Phosphorus pentoxide – P 2 O 5; Phosphorus sesquisulfide – P 4 S 3; Phosphorus ...
The names "caffeine" and "3,7-dihydro-1,3,7-trimethyl-1H-purine-2,6-dione" both signify the same chemical compound. The systematic name encodes the structure and composition of the caffeine molecule in some detail, and provides an unambiguous reference to this compound, whereas the name "caffeine" simply names it.
Copper(II) sulfate is an inorganic compound with the chemical formula Cu SO 4.It forms hydrates CuSO 4 ·nH 2 O, where n can range from 1 to 7. The pentahydrate (n = 5), a bright blue crystal, is the most commonly encountered hydrate of copper(II) sulfate, [10] while its anhydrous form is white. [11]
Cu(OH) 2 → CuO + H 2 O. A purer product can be attained if ammonium chloride is added to the solution beforehand to generate ammonia in situ. [10] Alternatively it can be produced in a two-step procedure from copper(II) sulfate via "basic copper sulfate:" [9] 4 CuSO 4 + 6 NH 3 + 6H 2 O → Cu 4 SO 4 (OH) 6 + 3 (NH 4) 2 SO 4
2 H 2 S + 3 O 2 → 2 H 2 O + 2 SO 2 (−1036 kJ/mol) The sulfur dioxide then oxidized to sulfur trioxide using oxygen with vanadium(V) oxide as catalyst. 2 SO 2 + O 2 ⇌ 2 SO 3 (−198 kJ/mol) (reaction is reversible) The sulfur trioxide is hydrated into sulfuric acid H 2 SO 4: SO 3 + H 2 O → H 2 SO 4 (g) (−101 kJ/mol)
Hydrated copper(II) phosphate precipitates upon addition of a solution of alkali metal phosphate to an aqueous solution of copper(II) sulfate. [4] The anhydrous material can be produced by a high-temperature (1000 °C) reaction between diammonium phosphate and copper(II) oxide. [5] 2 (NH 4) 2 HPO 4 + 3 CuO → Cu 3 (PO 4) 2 + 3 H 2 O + 4 NH 3
Cu 2 O + (CH 3 O) 2 SO 2 → Cu 2 SO 4 + (CH 3) 2 O. The material is stable in dry air at room temperature but decomposes rapidly in presence of moisture or upon heating. It decomposes into copper(II) sulfate pentahydrate upon contact with water. [4] Cu 2 SO 4 + 5 H 2 O → Cu + CuSO 4 · 5 H 2 O
