The main gases present in water that can cause corrosion are oxygen and carbon dioxide. These gases can react with metal surfaces, leading to the formation of corrosion products such as rust. Other gases, such as hydrogen sulfide, can also contribute to corrosion under certain conditions.

What metals are most affected and least affected by metal corrosion What causes metal corrosion Hows is metal corrosion caused by water and how is it related to it?
Iron and steel are most affected by corrosion, while metals like gold and platinum are least affected. Metal corrosion is caused by the reaction of metals with oxygen and water, leading to the formation of oxides or salts on the metal surface. In the presence of water, the metal corrodes much faster as water facilitates the transfer of electrons between the metal and oxygen, accelerating the oxidation process.
What two things is needed to make iron rust?
Answer 1: Salt and water especially if they are both present.Answer 2: Wrong. Water yes, but also oxygen, salt speeds up the reaction:Oxygen present in water and salt causes corrosion. Salt is hygroscopic in nature and it attracts the water. Water is required for corrosion and salt speeds up the process.
Which has more dissolved gases in it-hot water or cold water?
Cold water generally has more dissolved gases than hot water. This is because gases are more soluble in colder temperatures compared to warmer temperatures. When water is heated, its capacity to hold dissolved gases decreases.
Why does steel wool corrode from water?
Steel wool is made up of iron, which is prone to corrosion when exposed to water and oxygen. Water provides the necessary electrolytes for the corrosion process, leading to the formation of iron oxide (rust) on the surface of the steel wool. Over time, this corrosion weakens the steel wool and causes it to break down.
What gas is present in exhaled?
carbon dioxide
What causes leaks in water heaters?
condensation corrosion
Why isn't silver used in water pipes?
It causes corrosion
What are all the environmental factors causing corrosion?
Corrosion, as in the corrosion of iron into rust, needs two environmental factors: 1. oxygen present in the atmosphere 2. water/moisture present in the the atmosphere
What gases were present in earths today atmosphere?
The main gases present in Earth's atmosphere today are nitrogen (about 78%), oxygen (about 21%), argon (about 0.93%), and carbon dioxide (about 0.04%). Other gases such as water vapor, methane, and trace amounts of other gases are also present.
Why can water form gases in the early morning when the air is clear?
Condensation of water vapor causes dew.
What two gases are present in unpolluted air?
carbon dioxide, and oxigen

Is water present in air?
Aside from bubbles, there is no "air" in water, however oxygen and other atmospheric gases, such as oxygen or nitrogen, may readily absorb into water. Water is after all made up of two atmospheric gases, hydrogen and oxygen.
What are the three main cases of corrosion?
There are 3 types of weathering Physical Weathering which is split into two parts a.Freeze-thaw-as water enters cracks and holes it freezes and expands dueing for the rock to form cracks and breaking of the rock bunion skin (Exfoliation)-As the rock heats up and expands by day, and cools and contracts by night, stress is often exerted on the outer layers. The stress causes the peeling off the outer layers of rock in thin sheets. 2. Biological weathering- the roots and animals burrow into rocks which causes them to break. 3. Chemical weathering- mineral dissolving in the water makes the water acidic which then eats away the rock and sometimes causes holes.
What is the deaerator device used for?
A deaerator device is a mechanism found on steam boilers. Its purpose is to remove oxygen and other gases from the water that is entering the boiler tank, since the presence of oxygen or gases can cause corrosion on the inside of the boiler.
What are the main causes of the degradation of metals?
The main causes of metal degradation are corrosion, wear and tear, exposure to high temperatures, and chemical reactions with other substances. Corrosion, in particular, occurs when metals react with their environment (such as oxygen and moisture) and deteriorate over time. These factors can lead to structural weakness, diminished performance, and ultimately failure of the metal component.
Corrosion of a nail in water?
When a nail is exposed to water, it can undergo corrosion through a chemical reaction with oxygen and water molecules, forming iron oxide, commonly known as rust. The presence of moisture allows for the oxidation of the iron in the nail, leading to its degradation over time. This corrosion process weakens the nail and eventually causes it to deteriorate.
