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.
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.
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.
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).
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.
so that we can dilute the consentrated bacteria (or whatever) into forming a single colony that can be idntifiied with the naked eye
