- Nickel(II) sulfate,
or just nickel sulfate, usually refers to the chemical compound with the
- This highly soluble
blue-colored salt is a common source of the Ni2+ ion for
- Several sulfate
salts of nickel(II) are known, all being paramagnetic.
- These salts differ
with respect to their hydration or subtle structural details.
- The salt is usually
obtained by dissolution of nickel metal or nickel oxides in sulfuric
- Aqueous solutions of
nickel sulfate reacts with sodium carbonate to precipitate nickel
carbonate, a precursor to nickel-based catalysts and
- Addition of
ammonium sulfate to concentrated aqueous solutions of nickel sulfate
- Nickel sulfate
occurs as the rare mineral retgersite, which is a
- The second
hexahydrate is known as nickelhexahydrite (Ni,Mg,Fe)SO4·6H2O.
heptahydrate, which is relatively unstable in air, occurs as
- This blue-colored
solid is analogous to Mohr's salt, Fe(NH4)2SO4·6H2O.
- The significance of
the patient’s patch test results, namely allergic reactions to nickel
sulphate, cobalt chloride, thiuram mix and colophony, can then be
explained relative to her work and the workplace environment.
- Nickel sulfate more
frequently determines allergic dermatitis due to contact; less known are
nassal inflamation & bronichical asthma caused by nickel
- Nickel compounds are
known to be human carcinogens based on sufficient evidence of
carcinogenicity from studies in humans, including
and mechanistic information, which indicates a causal relationship
between exposure to nickel compounds and human cancer.
- Micron size diameter
fibers of 2-acrylamido-2-methyl-1-propanesulfonic acid doped polyaniline
were prepared via electro spinning.
- The conductivity of
individual fibers was found to be lower than that of a cast film of the
same polymer. Using the electroless deposition technique, the fibers
were coated with thin films of nickel.
nickel and zinc ferrites synthesised using a microemulsion technique
were characterised by high resolution transmission electron microscopy
and vibrating sample magnetometry.
- Injection of nickel
produces distant tumors of the liver in some strains of mice.
- A basic
hypophosphite reduced electroless sulphate bath was chosen as the
plating bath, where nickel sulphate and iron sulphate were used as the
source of metals in the bath, and sodium hypophosphite served as the
reductant and source of phosphorus.
- The latter is
occasionally used as a calibrant for magnetic susceptibility
measurements because it has no tendency to hydrate.
- Ammonium ferric
sulfate dodecahydrate (Fisher) and nickel sulfate hexahydrate (Fisher)
were used as-received as precursor salts for iron- and
nickel-bearing powders respectively.
- Nickel compounds and
metallic nickel have many industrial and commercial applications
including use in stainless steels and other nickel alloys, catalysts,
batteries, pigments, and ceramics.
