The main difference between alkaline zinc plating and cyanide zinc plating is the type of bath used in the plating process. Alkaline zinc plating uses an alkaline electrolyte solution, while cyanide zinc plating uses a cyanide-based electrolyte solution. Alkaline zinc plating is considered more environmentally friendly compared to cyanide zinc plating, which contains toxic cyanide compounds.

What is copper plating used for?
Copper plating is commonly used for decorative purposes to create a shiny and aesthetically pleasing surface on various objects like jewelry, household items, and plumbing fixtures. It is also used for its excellent conductivity in electronic components and wiring, as well as for its corrosion resistance in industrial applications.
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).
An unwanted reaction between metals and the atmosphere and water?
This can lead to corrosion, or the deterioration of metal due to a chemical reaction with its surroundings. In the presence of oxygen and water, metals can undergo oxidation, forming rust or other compounds that weaken the material. This process can be prevented or slowed down through protective coatings, such as paint or plating, that create a barrier between the metal and its environment.
The purpose or objective of streak plating is what?
Streak plating is used to isolate individual bacterial colonies from a mixed culture by spreading cells across a solid agar surface in a way that thins out and separates the colonies. This technique helps to obtain pure cultures for further study or testing, such as identifying and characterizing specific bacteria.
Why is streak plating important?
so that we can dilute the consentrated bacteria (or whatever) into forming a single colony that can be idntifiied with the naked eye
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?
"The most common gold plating solution includes some form of cyanide, and either alkaline gold or neutral gold." "The best gold plating solution will be different for the type of material you want to gold plate. There are several varieties of gold plating, so depending on what type of gold and how soft, hard or bright you want it, that's what will determine the type of gold plating solution you want."
What company developed non-cyanide electroplating?
Sandia National Laboratories in Albuquerque developed methods for gold-plating onto microelectronic devices that did not use cyanide.
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.
Why is KCN used in Ag plating?
KCN is used in silver plating because it works as a complexing agent that helps to stabilize the silver ions in solution, allowing for a more even and controlled deposition of silver onto the surface being plated. It also helps to prevent the formation of unwanted compounds that could interfere with the plating process.
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 a common electroplating solvent?
A common electroplating solvent is a solution of the metal salt that will be deposited onto the object being plated. Common examples include copper sulfate for copper plating, nickel sulfate for nickel plating, and silver nitrate for silver plating.
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 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.
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
