Question

Q3. What are rust and rusting?
​

Answer 1

Answer:

Rusting : Also called iron rust. the red or orange coating that forms on the surface of iron when exposed to air and moisture, consisting chiefly of ferric hydroxide and ferric oxide formed by oxidation. any film or coating on metal caused by oxidation.

Rust: Rust is an iron oxide, a usually reddish brown oxide formed by the reaction of iron and oxygen in the presence of water or air moisture. Several forms of rust are distinguishable both visually and by spectroscopy, and form under different circumstances.

Answer 2

Rust :-

• rust is Hydrated Iron (III) Oxide, also known as iron oxide (Fe²O³), as it is caused when iron reacts with oxygen and water - this reaction is known as oxidizing. 

• Rust occurs when iron or its alloys, such as steel, corrode.

• Basically it is an iron oxide

• Rust occurs when iron or its alloys, such as steel, corrode.

Rusting :-

• Rusting is a chemical process in which ferrous (Fe(II)) reacts with oxygen in the presence of moisture (or water), to produce ferric (Fe(III)) oxides and hydroxides (which are called rust).

•  Rusting  is a chemical reaction (oxidation) of iron that occurs over a period of time as the bare metal surface comes in contact with oxygen present in the air or water

• When an iron object is left in moist air for a considerable time, rust is formed

• Rusting causes slow degradation of iron and its alloys.
