Why does moisture cause rust to form?

Answer 1

In order for corrosion to occur, at low - ambient temperature, is necessary that water on another electrolyte is in contact with the metal surface. When high moisture is present is the evironment then is possible that a film of water will be in contact with the metal surface and corrosion can take place. In an environment with very low moisture where the metal surfcace is always dry corrosion will not occur

Answer 2

The '''more''' dissolved oxygen in the elctroylte (solution) the '''more''' corrosion. Because if there is more dissolved oxygen, then there is more hydrogen ions, therefore the metal is more likely to corrode if it is exposed to more hydrogen ions. Therefore more electrochemical exchange, the hydrogen ions will pass into the metal, and the metal will lose electrons to the solution.

Answer 3

the humidity is H2O. 2 parts hydrogen which is a natural gas actually a mixture of metals and strong acids. So because Hydrogen is very soluble and because it is a gas the higher the temp the more of a reaction u will receive. typically humidity occurs at higher temperatures causing an obvious greater eruption of hydrogen embrittlment (when certain metals are exposed to hydrogen this process begins causing even steel to fracture and become brittle)

Answer 4

Moisture provides the necessary environment for a chemical reaction called oxidation to occur, which leads to the formation of rust (iron oxide). When iron or steel is exposed to moisture (typically in the form of water or humidity), it reacts with oxygen in the air to form rust on the surface of the metal. This is a slow process that weakens the metal over time.

Answer 5

There are various factors that affect corrosion that include the type of metal. Temperature, climate, humidity, and the presence of water affect corrosion.

Answer 6

Oxygen in the presence of water cause rusting; rusting is an oxidation reaction. The hydrated iron oxide (Fe2O3) is formed.
