Rusting - Iron + water + oxygen = iron oxide

I want to help you achieve the grades you (and I) know you are capable of; these grades are the stepping stone to your future. Even if you don't want to study science or maths further, the grades you get now will open doors in the future.

When your school books are SUPER boring and confusing so you go to magical You Tube’s search bar 😂

[ratchetthelastlombax]

don't forget about a grade of metal, it also varies best try is pure steel, most modern steel aren't pure steel it is also blended with other materials to slow down the rusting process and increase its strength

[fbirdinand]

I think in the Saltwater + Air, the reason the Galvanised Nail got rusted is that the Jar itself was full of rust.

[arsludi]

I desagree with you about the mass of the nails - the mass of the nails decreased after the rust formation but the mass of the nails + the rust > the mass of the nails before the rust prossess .

[mnty]

the nail is conductor and it rises out of oil so the oil layer didn't work as supposed to, you can clearly see the top of that nail rusted much more than the air one

Superficially rusting of iron required water and oxygen. Why? Water molecules within a droplet of water on an iron plate are constantly drifting around. They will  drift at higher velocities at higher temperature. Those dissolved oxygen molecules within the droplet of water will adhere onto those drifting water molecules. When the oxygen "atom" that adhered onto a drifting water molecules that slamming against a iron atom will force it to transfer some of its electrons to the oxygen "atom" before turning itself to oxygen anion or O(2-). The iron atoms will not spontaneously turn into Fe(2+). They have to be forced to transform to Fe(2+). Therefore at higher temperatures, rusting process on those iron atoms is higher. Subsequently, such oxygen anion or O(2-) slamming against a water molecule before transforming to two hydroxide anions or 2OH(-). Then, Fe(2+) will adhere with two hydroxide anions to form Fe(OH)2. Subsequently Fe(OH)2 will react with another OH(-) to form Fe(OH)3. Finally, two Fe(OH)3 slamming against one another will form Fe2O3.3H2O crystal. Such Fe2O3 is called rust of iron. The water droplet also has some presence of hydrogen cations or H(+). When the iron atom reacting with slamming oxygen "atom", some electrons that dissipated from the reacted iron atom will be channeled within the iron atoms. When hydrogen cations or H(+) slamming against the iron plate, they will mop up such "excess' electrons before reducing to hydrogen gas that adhered onto the iron plate. The presence of salt or NaCl within the droplet of water will act as catalyst in hastening the rusting process. Why? Molecular mass of water is 16 whereas the one of sodium is 23.9. Therefore sodium cations within the droplet of water have much higher velocities. Thus,  the oxygen "atom" that adhered onto drifting sodium cation  will slam against the iron atom much harder to force it to transfer its electrons to the oxygen "atom". Thus, the rusting process on iron atoms will be hastened with the presence of salt or NaCl within the droplet of water. If you are interested in real discoveries, I would recommend you to read my book, The Unification Theory - Volume One and you will be amazed with lots of new, interesting discoveries. In God I trust.

The video is very nice I registered ... you just help me how the iron nail stays the same but when touched it can be broken like a chalk ... thank you very much.

i am here due to an experiment we have to conduct on rusting but I as a procrastinator shortened the time to 3 days so now I hope my editing skills are good enough to make this look like mine

[AhmadFakhruraziABakar]

May i know the water volume decrease or not along the duration of experiment?

[dejectd]

I'm going to do this for my science fair project

[rosewhite---]

what happens if you get half a jar of iron powder, add water to the top of the iron to saturate it, pour off the excess water and evacuate all the air above the wet iron mixture?
Does the bottle fill up with hydrogen or other gas?

[magnuswootton]

if you put glycerine with the water it liquidates the rust.

[CUBETechie]

How can I rust the nail very fast? I need iron oxide.

[redskins-ever]

Hey did you happen to test this out on silver in a jar of salt water for a time, to test the effect on it!? thanks.

[AliyaMuslim.]

When you don’t understand in the exam worksheet so searched this up:

[exbladex]

Wow you created martian soil in one of them.

[earthsign]

Can you do an experiment with salt water and oil

[alezandracd]

this was very helpful, thank you very much mam.
