Sterling silver is an alloy made of 92.5% silver and 7.5% other metals, usually copper. It is considered a precious metal and is commonly used in jewelry and silverware.
Sterling silver is a type of metal alloy that typically consists of 92.5% silver and 7.5% other metals, such as copper. In this case, it is a hetero alloy because it is composed of two different types of metal elements.
Sterling silver is not a solution- it is a metal alloy. Not the same thing.
A silver plate would be a heterogeneous mixture if there is a metal alloy in it also. If it was pure silver, then it would be a homogeneous mixture. Assuming that there is a metal alloy comprised with the silver plate, it is most likely a heterogeneous mixture.
Since sterling silver is an alloy of 92.5% pure silver and 7.5% of another metal, 7.5% of the material is not pure silver.
The most common metal mixed with silver to form sterling is copper.Silver Jimwww.SilverChatter.com
