Nickel Sulphate Hexahydrate 98% AR 500 gr

SKU : O-5126.0500
CAS : 10101-97-0
Formula : NiSO4. 6 H2O
Grade : Analytical Reagent

Nickel sulfate has some uses in the laboratory. Columns used in polyhistidine-tagging, useful in biochemistry and molecular biology, are regenerated with nickel sulfate. Aqueous solutions of NiSO4·6H2O and related hydrates react with ammonia to give [Ni(NH3)6]SO4 and with ethylenediamine to give the complex [Ni(H2NCH2CH2NH2)3]SO4. The latter is occasionally used as a calibrant for magnetic susceptibility measurements because it has no tendency to hydrate.

Nickel(II) sulfate, or just nickel sulfate, usually refers to the inorganic compound with the formula NiSO4(H2O)6. This highly soluble turquoise coloured salt is a common source of the Ni2+ ion for electroplating. Approximately 40,000 tonnes were produced in 2005.
At least seven sulfate salts of nickel(II) are known. These salts differ in terms of their hydration or crystal habit.The common tetragonal hexahydrate crystallizes from aqueous solution between 30.7 and 53.8 °C. Below these temperatures, a heptahydrate crystallises, and above these temperatures an orthorhombic hexahydrate forms. The yellow anhydrous form, NiSO4, crystallizes in orthorhombic crystal system and in standard pressure decomposes to NiO in temperatures above 640 °C, before reaching the melting point. It melts only at high system pressure, using a constant volume method the melting point was found to be 1210 °C. The anhydrous sulfate is produced by heating the hydrates above 330 °C.X-ray crystallography measurements show that NiSO4·6H2O consists of the octahedral [Ni(H2O)6]2+ ions. These ions in turn are hydrogen bonded to sulfate ions. Dissolution of the salt in water gives solutions containing the aquo complex [Ni(H2O)6]2+.All nickel sulfates are paramagnetic.

Hello
Can we help you?
Labotiq focuses on a practical and precise field: laboratory supplies, chemical reagents, equipment, and plastic labware. This kind of work is all about accuracy, safety, and trust, because even small details can affect the final result. The same idea is becoming more relevant in digital entertainment, where choosing a platform also means paying attention to reliability, transparency, and user protection.Online entertainment has turned into an everyday habit, from streaming and mobile games to casino-style platforms and interactive services. Still, a good digital experience starts with clear rules, secure payments, licensed operators, and easy-to-understand information. Anyone interested in safe online leisure and the Spanish gambling market can find a useful reference in mejores casinos en España. The topic is not only about fun, but also about choosing platforms carefully, understanding how regulation works, and avoiding random decisions when money and personal data are involved.That creates a simple connection between the two areas. Labotiq supports laboratories with dependable products for controlled work, while trusted information about digital entertainment helps users feel more confident online. When reliability comes first, both laboratory processes and online services become easier to understand, safer to use, and more valuable in everyday life.
