7758-99-8 Usage
Description
Copper(II) sulfate pentahydrate is known as blue vitriol. It is an odorless blue crystal that readily dissolves in water. It is also soluble in methanol, glycerol and slightly soluble in ethanol. The highly toxic, non-combustible has a nauseating metallic taste and turns white when dehydrated. Structurally, in the pentahydrate molecule, each copper(II) ions is surrounded by four water molecules in the corners and the fifth water molecule is attached by hydrogen bonding. Copper (II) sulfate has many applications including preparation of Bordeaux mixture, a fungicide preparation. Electroplating, timber preservation and textile industry use copper (II) sulfate.

Application
Copper(II) sulfate pentahydrate has been used:as an additive in trace element solution preparation in solid glucose minimal media.as a component of adamsII solution in Pneumococcal media.in the preparation of alginate gel for drug encapsulation.Copper(II) sulfate is an inorganic Lewis acid commonly used to promote acid catalyzed organic reactions. It is used as a reagent for the synthesis of copper carbenoids. It can also act as an effective redox catalyst in combination with other mixed oxidizing systems.Copper Sulfate Pentahydrate Fine Crystals serve as the main ingredient for manufacturing Bordeaux and Burgundy mixtures that are used as algaecides, both on the farm and to ensure safe water supplies. Bordeaux mixtures are also employed to adjust and maintain copper deficient soils to optimum levels.
General Description
Blue crystalline granules or powder. Melting point 110°C (with decomposition). Non-combustible. Nauseating metallic taste. Odorless. White when dehydrated.
Air & Water Reactions
Slowly effloresces in air. Water soluble.
Reactivity Profile
Copper sulfate pentahydrate can be dehydrated by heating. Serves as a weak oxidizing agent. Causes hydroxylamine to ignite. Gains water readily. The hydrated salt is vigorously reduced by hydroxylamine [Mellor 8:292(1946-1947)]. Both forms are incompatible with finely powdered metals. Both are incompatible with magnesium, corrode steel and iron, may react with alkalis, phosphates, acetylene gas, hydrazine, or nitromethane, and may react with beta-naphthol, propylene glycol, sulphathiazole and triethanolamine if the pH exceeds 7 . Both act as acidic salts, corrode metals and irritate tissues.
Fire Hazard
Literature sources indicate that Copper sulfate pentahydrate is nonflammable.
Check Digit Verification of cas no
The CAS Registry Mumber 7758-99-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,5 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 7758-99:
(6*7)+(5*7)+(4*5)+(3*8)+(2*9)+(1*9)=148
148 % 10 = 8
So 7758-99-8 is a valid CAS Registry Number.

Vibrational spectra of copper sulfate hydrates investigated with low-temperature raman spectroscopy and terahertz time domain spectroscopy
Fu, Xiaojian,Yang, Guang,Sun, Jingbo,Zhou, Ji
, p. 7314 - 7318 (2012)
In this paper, the vibrational spectra of copper sulfate hydrates (CuSO4xH2O, x = 5, 3, 1, 0) have been investigated with low-temperature Raman spectroscopy and terahertz time domain spectroscopy (THz-TDS). It is found that the four groups of Raman bands between 90 and 4000 cm-1 can be assigned to lattice vibration as well as intramolecular vibrations of a copper complex, sulfate group, and water molecules. The variation of vibrational spectra during the dehydrated process are discussed in detail considering the transformation of the crystal structure, especially the bands between 3000 and 3500 cm-1, which are attributed to the v 1 and v3 modes of water molecules. In addition, as a complement of Raman spectra, the THz spectra at 0.1-3 THz indicate the absorption due to the low-frequency lattice vibration and hydrogen bond.

Kita, Itsuro,Matsuo, Sadao
, p. 792 - 797 (1981)
Difference in the isotopic partition at the water of crystallization of CuSO4*5H20 (the site preference) was estimated for the hydrogen isotopes.Fractional dehydration of CuSO4*5H2O under vacuum at 0 and 25 deg C was used to determine the isotopic ratio, the amount of dehydrated water, and the rate process of dehydration.The following results were obtained. (1) Two maxima occur in the isotopic ratio in the dehydration range, FA) and one bonded to the sulfate ion through hydrogen bonding (site B) was made.The site preference of hydrogen isotopes (δD.) was concluded to be -32.0+/-5.2 for site A and +22.6+/-20.9 for site B, where the δD value was referred to the isotopic ratio of the mother liquor from which the crystal formed.

Hydrothermal reaction of CuCN, K3[Fe(CN)6] with 4-(6-amino-2-pyridyl)-1,2,4-triazole (apt) afforded a coordination polymer [Cu7(CN)7(apt)2]n (1), while solvothermal reaction of CuSCN with apt in acetonitrile afforded a coordination polymer [Cu2(SCN)2(apt)]n (2). Complex 1 shows two-dimensional polymeric network with large hexagonal channels constructing by CuCN chains and tridentate apt ligands. Complex 2 shows two-dimensional polymeric framework assembled by ladder-like [Cu(SCN)]n chains and bidentate apt ligands, in which thiocyanate acts as a tridentate bridging ligand. Both polymers are thermal stable and strong fluorescent in the solid state.
