Why do iron objects turn reddish-brown when exposed to air?
you must have seen if you leave a bolt out in the rain , areddish brown layer is deposited on it's surface after few days. it is called rust.iron reacts with oxygen of the air ,in the presence of moisture,to form a substance called iron oxide which we called rust.
What is a reddish flaky coating that forms when objects containing iron corrode?
The reddish flaky coating that forms when objects containing iron corrode is called rust. Rust is a result of the oxidation of iron when exposed to moisture and oxygen in the air.
What color is iron oxide and how does it affect the appearance of objects it is present on?
Iron oxide is typically a reddish-brown color. When it is present on objects, it can give them a rusty or weathered appearance.
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.
Is rust alkaline?
No, rust is not alkaline. Rust is a reddish-brown oxide that forms on iron or steel when exposed to oxygen and moisture. It is a chemical compound known as iron oxide.
What chemical will turn reddish when exposed to water and oxygen?

What happen when iron is exposed to air?
When iron is exposed to air and moisture, it undergoes a chemical reaction called oxidation, which forms iron oxide, commonly known as rust. Rust is a reddish-brown compound that can weaken and corrode the iron, eventually causing it to deteriorate over time. Regular maintenance and protective coatings can help prevent rusting.
Does iron have any color?
Pure iron is grey. Iron compounds have different colours, for example iron chloride is yellow, iron(II) hydroxide is green and iron(III) oxide is red-brown.
Is ferrous oxide rust?
Ferrous oxide is a compound composed of iron and oxygen, while rust is the reddish-brown oxide that forms on iron or steel when exposed to oxygen and moisture. Ferrous oxide can eventually contribute to the formation of rust on iron or steel surfaces when exposed to the elements over time.
