Very simply the blood contains iron, the iron is used to carry oxygen in the blood stream, oxidised iron is in effect rust. The blood turns red due to this. When the oxygen is removed from te blood stream the iron is no longer oxidised thus the blood turns blue, hence the blue blood returning to the heart.

∙ 14y agoOlder sinks (and bathtubs) that were white (or similar colors) were coated with an enamel coating. This is similar to pottery, and prevents the surface from rusting by excluding air or water. Newer sinks that are silver colored are stainless steel. The iron is alloyed with other metals, usually nickel and chrome. This alloy resists rust because of its composition. A much earlier method of rust-proofing was to coat steel with a layer of zinc. Known as galvanizing, the zinc served to exclude water and air from the steel. It is still used on metal buckets, washtubs, etc.

∙ 12y agobecause if you look for iron oxidation we need to form fe2O3 , but in our blood the heme group contain one iron atom and surrounded by large hydrocarbon connected to which by four bonds with nitrogen atoms ,, structure which impair its normal oxidation , so it will provide a weak bond to allow the O2 to go to the tissue ..

What chemical reaction forms rust?
The chemical process is called rusting. It occurs when iron (or iron containing metals) reacts with oxygen and in the presence of water to form rust. It is a redox reaction; iron is oxidised and oxygen (gas) is reduced in this process.
How does rust affect magnets?
Magnetism is the "lining up" of atoms. Iron atoms line up easily and tend to stay lined up. Rust is iron plus oxygen plus space: since there is less iron in a given volume of rust than in the same volume of solid iron, there are fewer iron atoms present to be polarized.
Why blood do not gets rusted even though it contain iron?
see the haemoglobin in the blood is a coordination complex of Fe3+(iron) and prophyrin .. ... when iron is found in the form of free radicle then it corrodes by oxidation and hence rusts .. iron in blood cant rust
Do only iron compounds rust?
Iron compounds do not rust. Iron and its alloys can rust. Although other metals can corrode it is usually only called rust when it is iron that is corroding.
Why doesn't iron rust if it is covered in paint?
The tar blocks oxygen from getting to the iron. But tar is such a nasty substance! There are a lot of better rust proofers available for iron. A lot of people use oils (the process of seasoning a cast iron pan involves heating the pan very hot then applying fat to it, allowing the fat to work itself into the pores of the iron), waxes or just paint.
You get rust as the final product due to the reaction between iron and oxygen then why do not you get rust despite having both iron and oxygen in our blood?
because you need to have solid iron for it to rust
What element makes blood red?
There is a substance called iron in your blood. As you probably know, when iron is exposed to oxygen, it immediately starts to rust, which rust is red. Therefore, when the iron in your blood "rusts'' so to speak, it turns your blood red.
Is rust a physical or a chemical?
Rust would be a chemical change. Rust is often called oxidized iron because oxygen atoms combine with iron and turn red, just like the red blood cells in your blood stream. When the oxygen in your lungs meets the iron in your blood cells, or when the iron in a nail combines with oxygen in the air, you get that rusty red color.
Is pewter waterproof?
No it will not rust as it doesnt have iron in it, but it may corrode and turn black over time
If iron rusts outside our body why doesn't it rust in our blood?
Actually, it does. Rust refers to the oxidation of iron, and the hemoglobin of blood oxidizes and carries oxygen to all the other parts of the body in a complicated molecular process.
Can graphite rackets rust?
No they will not get rust they are not iron to get rust. only iron get rust.
Why doesn't sprite rust iron?
it probably will over a long time, but it doesnt have much oxygen cause the water is diluted so it wont rust quickly
Why does blood smell like rust?
Rust is brown because of the metals they form on. It is caused by the iron oxide coating typically found on iron and steel. The colors are caused by the reaction of that coating with moisture and oxygen.
What chemical reaction forms rust?

What is formed when iron combines with oxygen in the air?
Iron reacting with oxygen produces rust, Fe2O3 (Iron (III) oxide) or FeO2 (Iron (II) oxide) depending on the composition of the iron.
Why iron does not rust?
Iron does rust by reacting with oxygen.
