Rust will not occur where it is dry and humid
The conditions necessary for rusting are water (or water vapour) and air, specifically Oxygen. If one condition is absent and the other is present then rusting would not occur but if both are present then rusting will occur
Rusting occurs when iron or steel is exposed to oxygen and water, creating a chemical reaction that forms iron oxide (rust). The presence of both oxygen and moisture is essential for rusting to occur. Factors such as humidity, temperature, and the type of metal can also influence the rate of rusting.
The best conditions for rusting to occur are when iron or steel is exposed to moisture (such as water or humidity) and oxygen. The presence of these elements initiates a chemical reaction that leads to the formation of rust. Additionally, exposure to salt or acidic substances can accelerate the rusting process.
Rusting can occur due to other factors such as exposure to moisture or water, presence of oxygen, and the presence of certain acids or chemicals in the environment. Additionally, the presence of impurities in the metal can also accelerate the rusting process. High humidity, salty environments, and contact with corrosive substances can all contribute to the rusting of metals.
Rusting requires conditions such as moisture and air (oxygen).
For rusting to occur, iron must be exposed to oxygen and moisture in the air. This triggers a chemical reaction known as oxidation, which causes the iron to form iron oxide, or rust. Presence of an electrolyte such as salt can accelerate the rusting process.
yes,rusting of iron can occur in distilled water.In fact it occur even very fast because ionic content in distilled water is very less.So,rusting of iron occur in distilled water.
Rusting occurs more frequently in humid regions because moisture in the air provides the necessary conditions for the oxidation of iron to form rust. In arid regions, although there is less moisture in the air, the presence of certain pollutants or salts can accelerate the rusting process by providing an electrolyte for the oxidation reaction to occur more rapidly.
MOISTURE AND OXYGEN
Water and oxygen are needed.
Rusting is a chemical change because under it iron goes under oxidation and oxidation is a chemical process. Also, a physical change can be reversed but a chemical change cannot and rusting cannot be reversed. Hence also rusting is a chemical change.
Rusting typically requires the presence of oxygen in the gas phase, as this initiates the oxidation reaction that leads to the formation of rust. Additionally, moisture or water is also needed for the process of rusting to occur, as it helps accelerate the oxidation of the metal.
