Gold is a precious metal that has been used for centuries to make jewelry, coins, and other objects. It is also a valuable investment, and as such, it is important to know how to tell if gold is real. There are a few simple tests that you can do at home to determine if gold is real.
One of the most common tests is the acid test. This test involves applying a drop of nitric acid to the gold. If the gold is real, it will not react with the acid. However, if the gold is fake, it will turn green or black.
