Iron does not clearly alter in pure water or in dry air, but when both water and oxygen are present (moist air), iron corrodes. Its silvery colour changes to a reddish-brown, because hydrated oxides are formed. Dissolved electrolytes accelerate the reaction mechanism, which is as follows:
4 Fe + 3 O2 + 6 H2O -> 4 Fe3+ + 12 OH- -> 4 Fe(OH)3 or 4 FeO(OH) + 4 H2O
Usually the oxide layer does not protect iron from further corrosion, but is removed so more metal oxides can be formed. Electrolytes are mostly iron (II) sulphate, which forms during corrosion by atmospheric SO2. In sea regions atmospheric salt particles may play an important role in this process.
Iron (II) hydroxide often precipitates in natural waters.
What else can I help you with?
What happens when you add alum to water?
crystals form
What happens when you add dry ice to warm water?
There will be fake fog as it sublimes
What happens when CuSO4 dissolves in water and then Fe dipped in it?
The iron piece become covered with a layer of copper.
What happens if you add another atom of oxygen to a molecule of water?
H2O2 is the hydrogen peroxide.
What causes iron changing to rust when it reacts with water?
When iron reacts with water and oxygen, a redox reaction occurs where iron undergoes oxidation to form iron oxide, commonly known as rust. This process is accelerated in the presence of electrolytes, such as salts in water, which promote the flow of electrons, leading to faster corrosion of the iron. Rusting is a form of corrosion that weakens the iron structure over time if left unaddressed.
What happens to iron and sulphur when you add water?
The iron and sulphur split because the iron sinks and the sulphur floats so you can separate the mixture
What happens when air is combined with substances like iron and water?
Air, iron and water will cause the iron to rust.
Can rusting happens with iron nail when it is kept in distilled water?
Yes, rust happens to iron nail though it is kept in distilled water.
What happens to iron oxide when it is dissolved?
Iron oxide (Fe2O3) in insoluble in water.
What do you add to sulpuric acid to get iron sulphate?
You would add iron oxide (rust) to sulfuric acid to produce iron sulfate and water in a chemical reaction.

nothing
How can you make rust?
Take iron, add water and wait.
What happens if iron is submerged in water?
Nothing. It just sinks.

and add it to water
