if you apply to much heat to it can cause the copper to pool at the heat source. this happens because of the different melting temperature between the 2 metals. silver usually has about 7.5% copper in it.
If you dip your silver necklace in a solution of blue copper II sulfate, a chemical reaction would occur causing a layer of copper to deposit on the silver necklace through a process called electroplating. This would change the appearance of the necklace from silver to a copper color.
The most likely redox reaction that would occur is the reduction of silver ions to silver metal by copper atoms, with copper atoms oxidizing to copper ions in the process. This reaction would lead to the displacement of silver ions by copper atoms in the solution.
copper is placed above the silver in the ractivity series which indicates that copper is more reactive than silver . when a copper coin is kept immersed in a solution of siler nitrate ,silver from its solution will deposit on copper coin . copper slowly displaces silver from the silver nitrate solution and the colour of solution changes from colourless to blue due to the formation of copper nitrate . the copper coin will disappear and silver will percipate out .
It would be blue, or turquoiseincidentally the color of turqouise stone is also derived from copper, in fact most copper solution in inorganic chem are blue. This is owing to copper being commonly found in a (II) oxidation state and octahedral coordination geometry resulting in a similar crystal field spliting energy.
A single displacement reaction would occur, with copper displacing silver from the silver nitrate solution to form copper(II) nitrate and silver metal. The balanced chemical equation for this reaction is: Cu + 2AgNO3 -> 2Ag + Cu(NO3)2.
Yes you can get away with turquoise and silver, but I would recommend more of a copper brown color.

Copper has a reaction with skin that may turn it green or black. So if you have gold or silver jewelery since copper is one of the metals in these 2 to keep prices down this may be the most likely cause.

No it's 90% silver and 10% copper with out the copper the coin would be to soft to use
While I was in photography class in high school, we used to go into the dark room and put pennies in the fixing agent trays. The copper would attract the silver that was left behind in the trays due to the developing process. The longer you left the copper in the tray, the more silver would be attracted to it. Works with other metals as well. Hope this helps.
The color of a copper patch applied to a metal coupling would typically be a reddish-brown, similar to the natural color of copper.
Melting point of Gold = 1064.18 °C Melting point of Silver = 961.78 °C Melting point of Copper = 1084.62 °C Of cause an alloy of all three would probably have a eutectic melting behavour
Silver nitrate does not precipitate in this case; elemental silver does. In this reaction, silver nitrate reacts with copper to form elemental silver and copper II nitrate. The silver, which is a metal, is insoluble in water.
