What is the golden penny?
Generally, when people talk about golden penny, they talk about a normal penny that has been treated to give it a gold color. In some cases, however, Penny could actually be met with gold. And in some even more rare cases, Penny could have been accidentally affected by empty metal. Golden Penny is also the name given by an ancient British coin worth twenty pencils.
The creation of golden penny is a common scientific experiment, especially at primary and high school. Many teachers use it to discuss an ancient study of alchemy and how it is related to modern chemistry. It also shows some basic concepts of chemistry and at the same time provides a specific result that students can take home and which can be quite exciting for younger students.
To create a golden penny at home, you will need a normal copper penny, a bunsen burner and a mixture of sodium hydroxide and zinc. You will also want to wear the right safety equipment, includingbry and gloves and have a few pliers to handle the penny. Sodium hydroxide canE be very dangerous if it is unresolved, so it is important to take care of in every step. Children who want to produce golden pennies should ask for help from an adult or teacher.
The mixture of zinc and sodium hydroxide should be placed in a container and deployed on the Bunsen burner. It should stay on the heat until it starts to boil, at this point the normal copper of the penny can be dropped into the mixture. It should remain in the mixture for two to three minutes, and should then be removed by pliers and left to dry on a paper towel. The color at this point should be roughly silver, because Zink created a thin layer on the outside of the copper.
Furthermore, the silver penny should be held with pliers above the direct heat of the Bunsen burner until the color changes. As soon as the silver penny begins to turn with the raised penny, it should be removed from the heat and placed on an inaccurate surface to cool. Penny will now seem golden penny, although in fact, it was just that the heat caused the zinc to mix with copper. This is basically a metal known as brass, which is commonly wrong with gold, although it is much less yellow and has a completely different consistency. So the golden penny, which most people create, can be described more precisely as a brass penny.
Gold Penny can also refer to a coin used under the reign of King Henry III. Before his reign, most coins with a high value used in England were either from the Byzantine Empire or from Arabia, but during his reign in 1257 saw the need for a local currency that could handle larger transactions. So he had a golden penny created, which on the one hand introduced him to the throne, and on the other was a cross and flowers. Unfortunately, King Henry III determined the value of the golden pennyly low, given the real price of gold, and therefore most coins were melted to sell as pure gold, so the real golden penny from this era was quite rare.
