How could you test your gold jewelry to determine whether it is a pure compound or a mixture?

  • Chemistry - ,

    Pure gold (100% Au) is soft and all gold jewelry I know of is a mixture of Au alloyed with another metal. Have you seen the old old movies showing a seedy looking settler being paid with gold. They bite the piece of metal. If it is soft it is pure gold.
