What happens to gold if you put it in lemon juice?

When gold is placed in lemon juice, a chemical reaction occurs between the citric acid in the lemon juice and the gold. The citric acid reacts with the gold to form gold citrate, which is a gold salt. This reaction causes the gold to dissolve in the lemon juice, creating a gold-colored solution. This reaction is reversible, and the gold can be recovered from the solution by adding a base, such as baking soda, to the solution. This will cause the gold citrate to precipitate out of the solution, allowing the gold to be collected.
