What is the chemical difference between yellow gold and white gold?
From Wikipedia (see link to the left of this answer):
White gold is an alloy of gold and at least one white metal, such as silver or palladium. Like yellow gold, white gold is measured in Carats.
Its properties vary depending on the metals and proportions used. As a result, white gold alloys can be used for different purposes; while a nickel alloy is hard, strong and therefore good for rings and pins, white gold-palladium alloys are soft, pliable and good for white gold gemstone settings. The highest quality white gold is usually at least 17 karat, and made up of gold and palladium, and sometimes even trace levels of platinum for weight and durability, although this often requires specialised goldsmiths.
While some higher quality white gold alloys retain their shine and lustre, most will be coated with a very thin layer of rhodium. This will give the naturally more dull white gold a shine comparable to platinum or silver. Often white gold will require cleaning, or re-coating of rhodium at a later date.
Land O'Lakes yellow American cheese is yellow from the natural coloring from the seed of the tropical annatto plant.

These are two names for the same form of the element - there is almost no difference at all. White phosphorus is relatively transparent white, but gets a yellow tinge to it when exposed to air, where the surface oxidises which changes the optical properties (it also glows in the dark as a result of the oxidation).
Yellow popcorn comes in most corn kernel bags. Although it isn’t really yellow until you put butter on it, we define it as yellow because it is more yellow than “White” popcorn. White popcorn, the anomaly, comes from the bags of corn kernels that say “White Popcorn” on the label. Obviously, we define it as white because it is not yellow. Yellow popcorn pops larger but has more hulls. White popcorn has fewer hulls and…
I have rheumatoid arthritis and have tried both. The yellow is stronger (to me) than the white. Yellow 10-325 I need only 2 daily to 4 daily for the white. My pharmacy alternates between the 2. I am not going to refill the whites unless I can't find the yellows. This will probably require some legwork but it'll be worth it.
It is very easy to tell the difference between a yellow perch and white perch. However, many people mistake white perch for silver bass.

The difference between a road lane and a line is the direction of travel on the roadway. In a road lane situation, there are usually two lanes divided by a white dotted line, traveling in the same direction. If there is a center line, (yellow solid or yellow dotted) the direction of travel is one lane each way.
White gold and yellow gold jewelry differ in composition, color, and value. White and yellow gold are mixed with different metals after they are mined. For example yellow gold may be mixed with alloys of copper or zinc, whereas white gold is often mixed with silver. The more gold present in the final product the higher the karat, or value. Because white gold often contains more pure gold it is often valued higher.
