What objects are oxidising?
Objects that are oxidizing typically involve a chemical reaction in which they lose electrons. Examples include metals that rust when exposed to oxygen, fruits that turn brown when cut and exposed to air, and batteries that generate electricity through oxidation-reduction reactions.
How amethst get there color?
Amethyst gets its color from trace amounts of iron in its crystal structure. When exposed to natural radiation and heat in the Earth's crust, these iron impurities cause the amethyst to turn purple.
What metal goes black in the air?
copper,and some precious metals, when exposed to air, turn black, like silver(completely turns black when exposed to air),gold(black spots appear),and others,maybe platinum.
Why does porcelain turn brown when heated?
Porcelain contains impurities such as iron oxide that can cause it to turn brown when exposed to high temperatures. These impurities react with the oxygen in the atmosphere during firing, leading to the discoloration.
What causes iron to rust and lady liberty turn green?
Iron rusts when it is exposed to oxygen and moisture, causing a chemical reaction that forms iron oxide. The green color on the Statue of Liberty is due to oxidation of the copper in the statue's protective coating over time, forming a blue-green patina called verdigris.

What chemical will turn reddish when exposed to water and oxygen?
I think what you are reffering to is iron oxide which is commonly known as rust
Why do iron objects turn reddish brown when exposed to air?
Oxygen in the air reacts with the iron, making a reddish brown compound known as iron oxide. Iron is a transition metal and we havent covered them in chemistry yet so i dont know exactly why but i think the iron atom takes two oxygen's electrons to fill its outer shell.
Which metal will turn into rust if you leave it in the air?
Iron or steel will rust, this is called oxidation. It's a reaction between oxygen and iron or steel

Why does blood turn brown?
Blood turns brown when it is exposed to air for a period of time because the iron in the hemoglobin molecules oxidizes, causing the blood to change color.
Names of objects that rust?
Objects that rust are primarily made of iron and steel, which are metals that oxidize when exposed to oxygen and moisture. Common objects that rust include cars, nails, bridges, and outdoor furniture. Rust is a form of iron oxide that weakens the structural integrity of the metal over time.
What happens to trolls when they are exposed to daylight?
They turn to stone when the are exposed in the sun
Why is your black cast iron stove turning grey?
The black color of cast iron stoves can turn grey due to a process called oxidation. This occurs when the iron is exposed to oxygen and moisture, leading to the formation of iron oxide, which appears as a grey patina on the surface. Regular maintenance and cleaning can help prevent this color change.
Why does rock turn reddish brown?
Rock can turn reddish brown due to the presence of iron oxide minerals, such as hematite or goethite, that have oxidized and formed on the surface of the rock. This oxidation process occurs when iron-containing minerals are exposed to oxygen and water, causing the reddish-brown color to develop.
