Chemical Identifiers. Nickel sulfate can also be obtained as a hexahydrate ( (CAS: ) which is blue to emerald green, and as a heptahydrate () (CAS: ), which is green. Samples can contain variable quantities of water, depending on their previous exposure to moisture or conditions.
Molecular weight or molecular weight range Information on optical activity and typical ratio of (stereo) isomers (if applicable and appropriate) not applicable Description of the manufacturing process and identity of the source (for UVCB substances only) not applicable Degree of purity (%) (if relevant for the entry in Annex VI)
g/mol (molecular weight nickel sulfamate) / g/mol (molecular weight nickel sulfamate tetrahydrate) * 1098 mg/kg bw (LD 50 nickel sulfamate tetrahydrate) = 853 mg/kg bw. This LD 50 results in classification in category 4 (300 – 2000 mg/kg bw). In line with the DS, RAC agrees with the proposed classification of nickel sulfamate as Acute
Nickel sulfate, or just nickel sulfate, usually refers to the inorganic compound with the formula NiSO4(H2O)6. This highly soluble bluecoloured salt is a common source of the Ni2+ ion for electroplating. Approximately 40,000 tonnes were produced in 2005. It is mainly used for electroplating of nickel. In 2005–06, nickel sulfate was the top allergen in patch tests.

Description: The Technic High Speed Nickel Sulfamate FFP process is designed for high speed, high current density applications to produce a low stress, semibright, ductile nickel deposit from either a sulfamate or sulfate electrolyte. Chemical / Process: Nickel Plating Hard
atomic weight and the number of electrons involved in the electrochemical reaction. The number of electrons involved is designated the valency of the metal. The atomic weight divided by the valency is referred to as the chemical equivalent or equivalent weight of the metal. Faraday showed that the quantity of electricity required to deposit or dissolve

Brightnickel deposits are about 2 to 10%. High CurrentDensity Sulfamate nickel solutions will allow very high current densities compared with many other nickel solutions. At the same temperatune and agitation rate, sulfamate nickel will plate at 50 to 100% higher current density than a standard Watts for mulation.
Oct 19, 2017· A general approach to access sulfamate esters through preparation of sulfamic acid salts, subsequent activation with triphenylphosphine ditriflate, and nucleophilic trapping is disclosed. The method proceeds in modest to excellent yields to incorporate nucleophiles derived from aliphatic alcohols and phenols. This approach can be employed to furnish differentially substituted sulfamides.
