Cobalt(II) sulfate heptahydrate. Cobalt(II) sulfate is any of the inorganic compounds with the formula CoSO 4 (H 2 O) x.Usually cobalt sulfate refers to the hexa- or heptahydrates CoSO 4. 6H 2 O or CoSO 4. 7H 2 O, respectively. [1]
Lead styphnate – C 6 HN 3 O 8 Pb; Lead tetrachloride – PbCl 4; Lead tetrafluoride – PbF 4; Lead tetroxide – Pb 3 O 4 [205] Lead titanate – PbTiO 3; Lead zirconate titanate – Pb[Ti x Zr 1−x]O 3 (e.g., x = 0.52 is lead zirconium titanate) Plumbane – PbH 4
Aluminium sulfate is rarely, if ever, encountered as the anhydrous salt. It forms a number of different hydrates, of which the hexadecahydrate Al 2 (SO 4) 3 ·16H 2 O and octadecahydrate Al 2 (SO 4) 3 ·18H 2 O are the most common. The heptadecahydrate, whose formula can be written as [Al(H 2 O) 6] 2 (SO 4) 3 ·5H 2 O, occurs naturally as the ...
A detailed product analysis of a large-scale synthesis revealed that one minor by-product was [Co(en) 2 Cl(H 2 NCH 2 CH 2 NH 3)]Cl 3, which contains a rare monodentate ethylenediamine ligand (protonated). [2] The cation [Co(en) 3] 3+ is octahedral with Co-N distances in the range 1.947–1.981 Å. The N-Co-N angles are 85° within the chelate ...
The solution reddens litmus and is an astringent. Aqueous solutions are dark violet and turns green when it is heated above 50 °C. [ 1 ] In addition to the dodecahydrate , the hexahydrate KCr(SO 4 ) 2 ·6H 2 O, dihydrate KCr(SO 4 ) 2 ·2H 2 O, and the monohydrate KCr(SO 4 ) 2 ·H 2 O are known.
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 Cu 4 SO 4 (OH) 6 + 2 NaOH → 4 Cu(OH) 2 ...
A crystallographic study shows that the compound contains the Ce 2 (SO 4) 8 8− anion, where the cerium atoms are 9 coordinated by oxygen atoms belonging to sulfate groups, in a distorted tricapped trigonal prism. The compound is thus sometimes formulated as (NH 4) 8 [Ce 2 (SO 4) 8]·4H 2 O. [2]
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]
