 # Which of the following elements are the constituents of white gold alloys?
A. Gold and copper
B. Silver and palladium
B. Palladium and platinum
D. Copper and Palladium



The correct answer is B. Silver and palladium.

White gold is an alloy of gold and at least one white metal (usually nickel, silver, or palladium). Like yellow gold, the purity of white gold is given in karats.

White gold's properties vary depending on the metals used and their proportions. As a result, white gold alloys can be used for many different purposes: while a nickel alloy is hard and strong, and therefore good for rings and pins; gold–palladium alloys are soft, pliable, and good for white-gold gemstone settings, sometimes with other metals, like copper, silver, and platinum, added for weight and durability (although this often requires specialized goldsmiths). The term white gold is used very loosely in the industry to describe karat gold alloys with a whitish hue. The word white covers a broad range of colors that borders or overlaps pale yellow, tinted brown, and even very pale rose. The jewelry industry often conceals these off-white colors by rhodium plating; thus it is a common misconception that the color of the rhodium plating, which is seen on many commercial pieces, is the actual color of white gold.
