Here's the reactions:
O2 + 4 e- + 2 H2O → 4 OH-
Because it forms hydroxide ions, this process is strongly affected by the presence of acid. Indeed, the corrosion of most metals by oxygen is accelerated at low pH. Providing the electrons for the above reaction is the oxidation of iron that may be described as follows:Fe → Fe2+ + 2 e−
The following redox reaction also occurs in the presence of water and is crucial to the formation of rust:4 Fe2+ + O2 → 4 Fe3+ + 2 O2−
Additionally, the following multistep acid-base reactions affect the course of rust formation:Fe2+ + 2 H2O ⇌ Fe(OH)2 + 2 H+Fe3+ + 3 H2O ⇌ Fe(OH)3 + 3 H+
as do the following dehydration equilibria:Fe(OH)2 ⇌ FeO + H2OFe(OH)3 ⇌ FeO(OH) + H2O2 FeO(OH) ⇌ Fe2O3 + H2O
Basically what is happening is that Iron reacts with water and oxygen in the air, causing those reactions to take place. Rust, generally refers to Ferrium (III) Oxide. Which would be Fe2O3.
What else can I help you with?
What happen when iron reacts with salt water?
Rust ( iron hydrated oxides) are formed.
Is rust stronger than iron?
It depends on what you mean by "heavier." Rust is less dense than iron. However, if you allow 1 gram of iron to rust completely, you will have more than 1 gram of rust. if we have equal volume of pure iron and rust (ferric oxide) then rust is lighter than iron.
Which element in iron rust?
There is 1 Iron atom and 2 oxogen atoms in Iron rust.
What is the compound needed to make iron rust?
Iron rusts when it reacts with oxygen in the presence of water to form iron oxide. The compound needed for iron to rust is iron oxide, which is commonly known as rust.
What gas you needed to make iron rust?
Oxygen gas is needed for iron to rust. When iron is exposed to oxygen and moisture in the air, a chemical reaction occurs that forms iron oxide, which is known as rust.
What is rust and why does it happen?
Rust is oxidized iron.
What would happen when iron nails are kept in hot water?
rust, lots of rust.
What happen when iron reacts with salt water?
Rust ( iron hydrated oxides) are formed.
What would happen if your car is made out of iron?
Rust and be heavy.
What happen when iron react with oxygen and water?
When iron reacts with oxygen and water, the chemical reaction that forms is known as rust. This is considered to be corrosive for most metal elements.
Why does rust happen?
Iron reacts with oxygen in the air to from Iron Oxide, commonly Iron (IV) Oxide. Iron oxide is a weaker, more brittle material, and is reddish brown. So when you see rust, it is not longer the iron, but an entirely new material. It is like Dough to a burnt crust. It used to be the stronger dough, but has changed into something completely different which is easy to crumple.
Can graphite rackets rust?
No they will not get rust they are not iron to get rust. only iron get rust.
Why iron does not rust?
Iron does rust by reacting with oxygen.
What chemical reactions happen when you put iron in hot water?
oxidation occurs and rust forms on the piece of iron from the oxygen in the water
Which liquids rust faster?
Liquids do not rust, iron does, rust is Hydrated Iron (III) oxide, so the only substance which can rust iron is water
What does rust and iron form?
Rust is an iron oxide, Fe2O3.
What can happen to an iron object that is left outdoors?
it will be rusted because of the H2O and oxgen
