The chemical reaction that occurs is little particles in the air react with your skin and turns the color yellow. Iodine kills your skin and will eventually turn it black.

Is milk rotting a physical or chemical reaction?
Physical changes are like water turning into ice, they can be reversed. Chemical changes form a new substance. Soured milk can not be reversed, so it is chemical.
Is milk turning sour a physical or chemical change?
Milk turning sour is a chemical change.
Is carbonation an example of a chemical reaction?
No. Carbonation is simply dissolving carbon dioxide gas in a liquid. Only indirect chemical change occurs, and if you just let the carbonated liquid sit for a while, it will reverse itself. A chemical reaction involves the destruction and or formation of bonds, which does not occur during the carbonation proper. Thus carbonation is a physical change, not a chemical one. However, under pressure, water and carbon dioxide form carbonic acid (H20 + CO2 -> H2CO3) which makes most carbonated beverages slightly more acidic. This change reverses itself when normal atmospheric conditions are restored.

Can copper turning be used to test how pH affects copper corrosion?
If copper is present, the solution will turnblue...
Is silver more reactive than copper?
Suspend a copper wire in a solution of silver nitrate. Over the course of a few hours the silver nitrate will convert to copper II nitrate, turning the solution blue. Elemental silver will precipitate.
Is turning cloudy a chemical change?
A solution turning cloudy is evidence of a chemical change.
Is turning litmus paper red from blue a chemical change?
yes. it is a chemical reaction
Is rain turning to snow a chemical reaction?
No, it is a change of state.
Can a solution produced through a chemical reaction?
Yes when you carry out any chemical reaction you will have some product at the end of the reaction. The things with which you start your chemical reaction is called reactants and the things which you get at the end are the products. For every chemical reation there is a product obtained and often catalyst are also used in it.
Is a lobster turning red while cooking a chemical change?
Yes, it is a chemical change; a chemical reaction occur.
Is something turning copper to green a chemical reaction?
ya mon.
What is a balanced word equation for the reaction of cucumbers turning into pickles?
A chemical reaction for this process doesn't exist.
Is turning an egg into a pancake a chemical or a physical reaction?
chemical -you cant turn the pancake back into an egg :)
Is turning a penny gold a chemical or physical reaction?
Anything else then dropping it in molten gold is chemical
Is banana's turning black a chemical reaction?
No, some people say that but it is not true!
Is a flower wilting and turning from white to brown an example of chemical reaction?
Yes, because some chemical reactions are involved.
What indication is most suggestive of a chemical reaction?
A chemical reaction occurs when a chemical substance transforms into another. Typically, during chemical reactions, electrons shift from one substance to another when chemical bonds break and form. One method that can be used to detect a chemical reaction is by studying the change in temperature of either the chemicals themselves or of the vessel containing the reacting chemicals. For instance, mixing caustic soda (lye) with fat or oil produces an intense and potentially dangerous amount of heat, and ultimately results (assuming the correct proportions are used) in hand soap. Another method is to document the attributes of the chemical before the reaction (pH level, colour, viscosity, etc.) and after the reaction. This is far more useful when one wishes to later determine the path of the reaction (known as the "reaction equation"). For instance, using what's known as a "Universal Indicator Solution", one can add vinegar (an acid, which has a low pH), which results in a chemical reaction turning the solution red. Then, adding ammonia (a base, which has a high pH) turns the solution blue. Adding more vinegar would lower the pH of the overall solution, turning the solution back toward the red spectrum. This topic is complex, and the reader is encouraged to view the related Wikipedia link below for more information. As with all work in chemistry, be sure to take the necessary precautions prior to experimenting with chemical reactions!
