6H2O is green. reflective? 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
Peter Wood The Stables - Polegate, East Sussex, UK . The only sources I can find for this are very large bulk, so I decided to make it.Sorry, why am I being downvoted? Nickel Chloride is a green or yellow colored, crystalline inorganic compound that produces toxic gases upon heating. The amperage/voltage must be important. 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, … Nickel is a transition metal and Chlorine is a non-metal. Sorry if this is the wrong place.I have a respiratory and various glass containers.
6H 2 O is green. The solution evaporates the process of cooling, crystallization and washing so as to achieve the nickel chloride crystal. This will greatly speed the reaction and increase the yield. Good luck.I am happy that you are plating better. I do have HNO3 but don't want to create a mixture of nitrate and chloride so I guess i'll let things simply sit. What of secondary containment? 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. Add about 100mL of 29% HCl to the well-cleaned glass for every $0.30 you intend to leech. I have a respiratory and various glass containers.
in the goblet as I hook up the battery to the gold coin and the goblet. After two days, the becher exhibits a very pale greenish color, and there are quite a few bubbles on the nickel itself.Hm, okay then. I do make my own copper sulfate and silver chloride. Boric Acid is a buffer and helps keep the solution stable. I would be very grateful if you could please tell me how to make nickel sulfate for plating as it is not easy to obtain in UK (only in large amounts). If this involves costly, hazardous chemicals I could back off but I'd like to know what would be involved.Electroplating does involve haz-mat chemicals. The nickel chlorides are deliquescent, absorbing moisture from the air to form a solution. Hi, I am looking to prepare some nickel chloride for purposes of electro plating. A process for producing anhydrous nickel chloride comprising treating hydrated nickel chloride at a temperature of about 200 to about 240°C for a time less than 12 hours. Inhibition of hydrolysis should be taken note in the process. Nickel is much lower on the electromotive series than zinc, and the reaction is less energetically favorable- in other terms, slower. When heated to above 140℃, it completely loses crystal water to generate yellow brown powder. You can buy or get samples from the major supply houses.A discussion started in1998 but continuing through 2020I hope I didn't read things wrong and offend you, but while this forum can be useful for answering specific questions, as Tom answered with the formula for Watt's Nickel, it's not the most efficient way to introduce people to electroplating; books are "tutorial", proceeding from scratch to deep knowledge over the course of a hundred pages, whereas web postings tend to either be repetitive to a maddening degree or over our heads; plus people may wrongly assume they can just jump in without safety & environmental hazards -- especially when they go unmentioned in threads like this (as evidenced by the first 7 entries)-- whereas they are prominently mentioned in most books. Often people will try to plate using just nickel chloride but the nickel content will not be enough, likewise with nickel sulphate the conductivity will not be enough. The only sources I can find for this are very large bulk, so I decided to make it. I believe that mixing pure nickle and hydrochloric acid will produce what I need but I need to know the proper amounts. But it may also be ammonia, or an alcohol. The only nickel plate for stainless i have found requires nickel chloride.I believe that mixing pure nickle and hydrochloric acid will produce what I need but I need to know the proper amounts.If I had to prepare this from scratch, I would use HCl gas or Cl2 gas and nickel powder.I don't know why you were downvoted. There's some very weak bubbling after an hour, but nothing to write home... no "green" color at all.So i'll try just heat this weekend, hoping to keep the reaction under control. I believe that mixing pure nickle and hydrochloric acid will produce what I need but I need to know the proper amounts.
leveled? It is operated at 140° F, pH 4.0, and current density of up to 40 ASF.
Not too expensive, but still really nice. If you try to boil off the water you will convert some of that NiCl2 to Nickel oxide and hydroxide. Is there a better sub to ask this question? Without brightening agents, this will not be bright as plated; you'll have to buff it for brightness.It may depend on what you mean by "smooth": bright? Salts of nickel, like many other metal’s salts, have a strong affinity for polar ligands. Uses of nikil chloride NiCl2 and its hydrate are occasionally useful in organic synthesis.
