Fake goods in gold jewelry are often mixed with fish eyes. Some criminals in the society often impersonate gold for scam activities with brass (copper, zinc alloy). Because brass is simply similar in color and shape, it is very similar to gold, so it is difficult to distinguish between distinguishment . Please design an experimental plan to identify the true and false gold, and require the experimental method, phenomenon and conclusions. See if there is an air bubble, if there is a bubble, if there is a bubble, the fake gold is immersed in the silver solution of the nitrate solution.
