Painting of iron prevent it from rusting because it prevent the iron articles coming in Contact with oxygen, or water vapours present in the air.

∙ 12y agoRusting occurs when the moisture and oxygev in the air react with iron. Whereas if we galvanise it the iron has no contact with air thus it prevents rust.
Wiki User
∙ 8y agoIt will prevent the direct contact of Iron with the air or oxygen by covering its surface
So it will not allow the reaction between Iron and Oxygen
Wiki User
∙ 14y agoThe steel is coated with a zinc coating which binds very tightly to the steel. Zinc doesn't rust so it protects the steel.
Wiki User
∙ 10y agoThe paint acts as a barrier between the oxygen in the air and the iron, therefore reducing the chance of the two reacting with one another, which prevents rusting.
Wiki User
∙ 13y agoIt acts as a barrier to reduce the rate at which fuels for corrosion (water and oxygen) reach the surface of the iron/steel
Wiki User
∙ 12y agoIt prevents moisture, which is the main force behind corrsion, from reaching the surface.
Wiki User
∙ 11y agoIron reacts with oxygen to form iron oxide(rust). The paint acts as a barrier preventing the oxygen from reaching the iron. This prevents rusting.
Wiki User
∙ 11y agoPaint keeps oxygen from reaching the iron. With no oxygen you can't have rust.
Wiki User
∙ 16y agoIt stops the oxidation of the metal

Is rusting iron a physical change in science?
no rusting iron is not a physical change it is a chemical change
What are the ways of preventing rusting?
Rusting is the oxidation of iron. To prevent rusting you must prevent oxygen from coming into contact with the product. This is normally acheived by applying a barrier of oil in working environments. Products are available for storing materials for long periods to avoid rusting. These have a more waxy nature than oil and would not be suitable to use to stop rusting in a mechaincal item. Of course if you want to prevent rusting and for it to look nice. various paints and lackers can be applied. Chemical coatings can also be applied to prevent rusting. Or simply keep the item clean and dry and rusting can be slowed.
What kind of change iron to rust?
Iron rusting is a chemical change in which iron reacts with moist air to form fe2o3 commonly known as rust, a brown coloured coating.
Is a rusting bicycle a physical or chemical change?
It's not the rusty bike it's the rusting of the bike. rust forms in a process called oxidation, or when iron comes in contact with oxygen. Also one reason you can tell it's a chemical change is when you can't reverse the process. Or when it involves changing the chemical compound.
Does sugar water cause rust?
Iron is a highly reactive metal and when exposed to air, water and moisture, it starts reacting with them and forms rust. Basically rusting is the reaction of iron with oxygen and iron is nothing but iron oxide(Fe2O3). Iron things can be protected from rusting by using paints, galvanization etc.
What protects iron from rusting if attached?
Paint or enamel can protect iron from rusting.
Why do you apply paint to iron articles?
Paint can protect iron from rusting, especially if it is the right kind of paint - you would not want to use a water based acrylic paint, since the water in the paint would promote rusting, rather than preventing it.
How does painting on an iron gate prevent it from rusting?
I'll give a non chemist answer but a wise answer... logically, you are covering it with a mixture (correct this If Im wrong), preventing it to have contact with the oxygen in the atmosphere. Therefore preventing the iron to oxidize :)
How does paint stop rust?
Rusting is caused due to exposture of iron to moisture. When iron articles are painted, it is not exposed to the atomospheric moisture. This is how paint stops rusting
Why is it necessary to paint iron gates?
To stop them rusting.
Why you do apply paint on iron article?
when we apply paint on iron articles moist air cannot attack iron and prevent rusting
What should we do to the iron to prevent rusting?
Keep it dry. Paint it Galvanize it
Why is galvinising used?
to protect iron (or other metals from rusting).
Why are iron objects painted before use?
Iron objects are painted before use to prevent them from rusting. Paint does not let the moisture to get inside it and prevent iron's quality from rusting.
Which metals can be used to protect iron from rusting and how?
Try covering it in Zinc
Why do you need to protect iron from rusting?
Otherwise the iron will rust and eventually disintegrate and become unusable
How can iron be treated to stop it from rusting?
cover in oil, paint, grease or plastic. or galvanise it
