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?
Corrosion is a chemical reaction; corrosion of iron is the reaction with water in the presence of oxygen. Metals as Pt, Au, Ta, Rh, Ru, etc are less sensible to corrosion.
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 pollutant causes the greatest corrosion of steel structures?
Answer 1: oxygen and carbon in the air :-) Answer 2: Depends on what type of corrosion you are referring to. Rust and corrosion are typically used interchangeably. Rust is one type of corrosion. Corrosion is essentially the disintegration of a engineered material. Rust is a chemical reaction, but there are other chemical reactions that cause corrosion of steel (typically acids). Other types of corrosion include fretting, erosion, cavitation, and galvanic reactions. There are many methods to prevent corrosion. One of the most versatile of prevention solutions is electroless nickel plating. Electroless nickel resists all types of corrosion.
What does soda have in it that removes corrosion?
Carbonated Water
How stomata reacts with water?
When light hits the stomata it activates photosynthetic K+ pumps. These cells pump potassium ions into the guards cell around the stomata. Water is attracted to the potassium ions and thus enters the guards cells. This causes the guard cells to swell, but the rigidity of the one side causes that side to bow inwards, this creates an opening for gases to exchange in the leaf. This opening is the stomata. When water is not present, the stomata will not open.
What causes leaks in water heaters?
condensation corrosion
What are the main causes of the degradation of metals?
water 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
Why isn't silver used in water pipes?
It causes corrosion

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.
Gases present in venus?
96.5 carbon dioxide 3.5 nitrogen 1 ./. argon
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
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.
Why do things rust in salt water?
The salt (the ion chloride) in the ocean causes corrosion which rusts metals or any other substances.
