What is copper plating used for?
copper plating is given for good finishing of metal, for luster .
What is hydrogen sulfide used for?
AnswerIndustrially, cyanide is used in addition of carbon to certain organic compounds and in gold ore processing. In society, it has been used as a form of execution (the gas chamber).
The purpose or objective of streak plating is what?
to under stand the principle of bacterial isolation
A process used to plate metal on to a substance?
The key to plating metal is electrochemistry. Plating is electrodeposition. Connect the negative lead of a DC supply to the part to be plated, and connect the positive lead to an electrode in a tank of the plating solution. Stick your part in, turn on the juice, and wait for your results. The plating solution is basically a metal salt, and the metal in the metal salt is the one you're going to be plating onto your part. Yes, the part has to be super clean and free of any contaminants, but you knew that. Let's look at an example. Copper sulfate, which has CuSO4 as it's chemical formula, is in solution in the tank. The copper sulfate separates into Cu++ and SO4-- ions, which float around in solution. Your part is connected to the negative electrode. The power supply gives electrons to the copper ions that touch the part, the Cu++ ions we mentioned, and they become electrodeposited on the part as copper atoms. There are a number of different chemical compounds that can be used in electroplating. Our example was a sulfate. There are arsenides, carbonates and other chemical compounds available for use in electroplating that have the desired metal in them. Whether it's chromium, nickel, silver, gold or just about any other metal you can think of, you can plate it. Note that some precious metals are plated on with a sponge-tipped wand that is connected to a wire and then dipped in the electroplating solution. Gold is frequently plated on an object in this way because of the high cost of filling a tank with a solution of a gold salt. Wikipedia has more information, and a link is provided.
Why are kitchen gas burners coated with chromium?
we often find a chromium plating on kitchen gas burners which not only provides a shiny appearance but also helps to avoid corrosion and effects of 'wear and tear' and scratches. some coatings help to increase the strength of the base metal.
What has the author W Dingley written?
W. Dingley has written: 'Stable copper cyanide plating baths' -- subject(s): Cuprous cyanide, Plating baths
What is the formula for silver cyanide?
The molecular formula for silver cyanide is AgCN.Silver cyanide is often used in silver plating.
What is the best gold plating solution?
There is no definitive "best" gold plating solution as it depends on the specific application and desired outcome. However, a commonly used gold plating solution is one that contains gold cyanide, which provides good conductivity, brightness, and durability. It is important to consult with a specialist or conduct thorough research to select the most appropriate gold plating solution for your specific needs.
What company developed non-cyanide electroplating?
Sandia National Laboratories in Albuquerque developed methods for gold-plating onto microelectronic devices that did not use cyanide.
Why is KCN used in Ag plating?
Normally AgCN but not KCN is used to reduce free cyanide in the plating bath from CN- to Ag(CN)2- in order to prevent cyanide immersion forming. Addition AgCN make the bath chemical equilibrium more stable as accumulation of free cyanide. There is no reason why KCN is used (CM Lew, Malaysia).
In the electroplating of gold the electolyte used is?
Gold-VA is a strong acidic cyanide based gold-electrolyte.It is used in gold plating.
What is a common electroplating solvent?
The solvents used to dissolve plating metals often were highly toxic. Cyanide, for example, was a commonly used solvent.
What is the difference between lacquer and silver plating?
Laquer is clear paint applied to almost any prepared surface, while silver plate is silver attached by means of a sort of electro plating methods to a metallic surface .
What is the difference between plating and coating?
Plating is used for conductive materials while coating is used for non-conductive materials. My brass horn is silver plated while patio table is plastic coated.
What is the equation for silver cyanate?
Well this is quite a good question when i was in high school which was many years ago i learnt all this stuff. The answer is that Silver cyanide is the chemical compound with the formula AgCN. This white solid forms upon treatment of solutions containing Ag+ with cyanide. This precipitation step is used in some schemes to recover silver from solution. Silver cyanide is used in silver-plating
What is the difference between brushed pewter and brushed nickel pewter?
The brushed nickel is nickel plating on brass that has been lacquer coated and made to appear matte or dull. The brushed texture limits the ability of fluid to bead on the material surface. The main difference between the two is a slight color difference.
Is the 24k electroplate golden 49er series pure gold?
Yes and no. One common chemical used in electro plating is gold cyanide. By applying an electrical current to copper or silver submerged in gold cyanide, a thin layer of gold is deposited on the object. It may be 24K, but is so thin it can be scraped off, and has virtually no value.
