What is added to give gold alloy a white color?
Palladium
Silver
Nickel
Platinum
The correct answer is: Palladium
Gold is naturally a yellow-toned metal, and alloying it with other metals can result in different colored alloys. While silver and platinum are both frequently used to make white gold, palladium is the most common alloy used to achieve a white color. Nickel is sometimes added to gold alloys to make a stronger white gold, but this can cause allergic reactions in some individuals. Therefore, palladium is the best option for giving gold alloy a white color.
