A bottle of the gold is put on a drop of nitric acid on the gold jewelry to see if it reacts. After dripping nitric acid on gold jewelry, if nitric acid will produce a green reaction, then it is a fake. If the reaction that the nitric acid is dripped on the gold jewelry is a milky white response, it means that such gold jewelry may be a gold -plated sterling silver -plated silver -plated silver -plated silver It is not a real gold jewelry. If you drip nitrate on the gold jewelry, there is no chemical reaction, indicating that your gold jewelry is real gold.
