Would you expect jewelry made of an alloy of silver and copper to tarnish(react) in an environment where chlorine fumes exist? Why or why not?
Im assuming yes because both silver and copper metals react with chlorine gas...I don't know if I am correct in answering so.
I would assume that both Cu and Ag would react with Cl2 gas. At least to the tarnish stage.
Yes, you are correct in your assumption that jewelry made of an alloy of silver and copper would tarnish or react in an environment where chlorine fumes exist. Both silver and copper metals can react with chlorine gas.
Chlorine gas is a strong oxidizing agent, meaning it readily accepts electrons from other substances. When silver comes into contact with chlorine gas, it forms silver chloride (AgCl), which is a grayish-white compound that appears as tarnish on the silver surface.
Copper, on the other hand, can react with chlorine gas to form different copper chloride compounds, such as cuprous chloride (CuCl) or cupric chloride (CuCl2). These compounds can also appear as tarnish on the copper surface.
Therefore, in the presence of chlorine fumes, the silver and copper in the alloy would both undergo reactions with the chlorine gas, resulting in tarnish or discoloration of the jewelry.
Yes, you are correct. Jewelry made of an alloy of silver and copper, also known as silver-copper alloy or sterling silver, would be expected to tarnish or react in an environment where chlorine fumes exist.
Both silver and copper metals are reactive to chlorine gas. When silver comes into contact with chlorine, it forms silver chloride, a compound that is known to be tarnish. Copper, on the other hand, can react with chlorine to form copper chloride, another tarnish compound.
So, when chlorine fumes are present, they can react with the silver and copper in the alloy, causing the jewelry to tarnish. Tarnish often appears as a dull or black coating on the surface of the metal, which can negatively affect the appearance of the jewelry.
To protect your jewelry made of silver-copper alloy from tarnishing in an environment with chlorine fumes, it is recommended to store it in an airtight container or bag when not in use. Additionally, removing the jewelry before coming into contact with chlorine-based cleaning products or swimming pools can also help minimize tarnishing.
