6H2O is green.
Sorry you don't like the service.Best of luck in your plating work, but please consider a haz-mat training seminar if you're continuing to mix chemicals. Hi, I am looking to prepare some nickel chloride for purposes of electro plating.
I have a respiratory and various glass containers.
Add about 100mL of 29% HCl to the well-cleaned glass for every $0.30 you intend to leech. IIRC people with pre-existing allergies (hay fever, bees etc) tend to be more sensitive.Be careful with nickel salts, as they are carcinogenic to some degree.Hi, I am looking to prepare some nickel chloride for purposes of electro plating. One large beaker of chrome plating solution broken on the garage floor can poison all the wells for blocks around.The very easiest way to clean onesy-twosy items is to scrub them with a solution of powdered pumice, a little detergent, and warm water, using an old-fashioned tampico scrub brush.
i just covered the jar with a "watch glass" that would let the H2 out so pressure wouldnt build upWell aqua regia will certainly work, but I expect it is a "sledge hammer to crack a nut" approach. The solution evaporates the process of cooling, crystallization and washing so as to achieve the nickel chloride crystal. How to make nickel sulfate for plating 2006. The most common nickel plating solution is Watts' Nickel.
This is an ionic compound.
Donovan, and Raleigh Gilchrist A method is described for the preparation of cobalt-free nickel chloride, which consists in the repeated precipitation by hydrogen chloride of nickel chloride dihydrate from a mixture
Is there a reagent that I can safely and carefully add to the content to kickstart the reaction?Nickel is much lower on the electromotive series than zinc, and the reaction is less energetically favorable- in other terms, slower.I suspect the oxidation is a kinetic problem rather than a thermodynamic problem, but tbh NiCl26H2O is so cheap I would just buy a little bit!I usually order stuff from ProLab that I can't make myself and is relatively inexpensive.Already have an account?
I made some for plating last weekend out of nickel wire, plain kitchen vinegar, a pinch of salt, and a voltage source. Boric Acid is a buffer and helps keep the solution stable.
What of secondary containment? Nickel(II) chloride, in various forms, is the most important source of nickel for chemical synthesis. It is operated at 140° F, pH 4.0, and current density of up to 40 ASF.
Nickel is much lower on the electromotive series than zinc, and the reaction is less energetically favorable- in other terms, slower.
Not too expensive, but still really nice. The over-all yield of high-purity nickel salt was approximately 85 percent.
It consists of: - 225 to 300 g/l NiSO4.6H2O (nickel sulfate hexahydrate) - 37 to 53 g/l NiCl2.6H2O (nickel chloride hexahydrate) - 30 to 45 g/l H3BO3 (boric acid). Please advise. The amperage/voltage must be important. I have a respiratory and various glass containers. If a neighborhood child develops cancer of any type for any reason, and her parents find out you were chrome plating in your garage, God help you.Hope this helps anyone new to the process.
Nickel chloride is used in electroplating, in nickel catalysts and to absorb ammonia in industrial gas masks. If you try to boil off the water you will convert some of that NiCl2 to Nickel oxide and hydroxide.
Sign in here.Outside or in a fume hood, you could add nitric acid or sodium nitrate (though you will need to remove the sodium chloride from the product) to make the oxidizing mixture known as aqua regia (or poor man's aqua regia for the sodium nitrate version, potassium nitrate would be okay as well- don't use ammonium nitrate).
