acid like salt or such as baking soda could speed up oxidation speed. also acid rain also affects metal so salt would speed up the process

Why would a metal corrode more quickly in a salt water than distilled water?
In a medium of lower pH (acidic), the rate of corrosion is high. If the pH of medium is below 3 (approximately), even in absence of air severe corrosion takes place due to rapid evolution of hydrogen at cathodic areas, facilitating anodic oxidation of the metal and dissociation of corrosion product, exposing fresh metal surface for corrosion. In distilled water (pH about 7), rate of corrosion is relatively lower.
Is corrosion of aluminum metal a chemical?
Corrosion is a chemical process.
What is the metal that speed up corrosion?
Any metal that is higher than iron in the electrochemical series coupled to it will speed up the corrosion. As an example, a copper pipe in contact with steel will accelerate the corrosion of the steel.
When metal enters a chemical reaction what is it called?
The process called when metal is destroyed by a chemical reaction is called Corrosion. Electrochemical of oxidation of metals reacts with oxygen thus corrosion will occur on metals.
Explain dry corrosion with an example?
Dry corrosion occurs when the metal reacts with oxygen in the air.
Is corrosion of metals is physical?
corrosion of metals is a chemical reaction between metal and oxygen in atmosphere. Oxidation of metals called corrosion. It affects the physical properties of metal in either way like rusting, colour change, life cycle shortening etc.
Polarization is a measure of?
Polarization curve is measuring the corrosion rate of the metal with respect to current and voltage.

What is immersed corrosion?
Immersed Corrosion refers to a type of metal corrosion when the metal is immersed in a liquid.
What is metal corrosion?
Metal Corrosion or Metallic Corrosion can be defined as the destructive attack of a metal through interaction with its environment.The most common example is Rust, an iron oxide Fe2O3, that is the consequence of the Corrosion process of Iron.
What makes the corrosion rate higher in industrial areas than in urban areas?
Taking a look at the industrial areas,the corrosion rate seems to be higher since the industrial area can be said to be a combination of both an urban centre and a rural centre and invariably has a corrosion rate= corrosion rate of urban + corrosion rate of rural areas
Is corrosion of aluminum metal a chemical?
Corrosion is a chemical process.
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.
How does the genre of music affect the heart rate?
Heavy metal music affects your heart rate because it is loud and people are screaming
Is rust a form of corrosion?
Yes. Rust is oxidation of the metal, a form of corrosion (chemical destruction) that weakens metal.
Which metal could be used to coat another metal to protect it from corrosion?
Tin could be used to coat another metal. It is done to prevent corrosion.
Why does corrosion rate of no value on localized corrosion?
in my opinion, the value of corrosion rate obtained from certain reading is generally determine general corrosion rate, regardless what type of corrosion occur on a specific surface. in localized corrosion, where only some spots on surface is exposed to corrosion and other may be covered by film and etc. From my time of study, still didn't fine any research that can determine corrosion rate of localized corrosion unless u have a really micro- instrumentation that can monitor corrosion on the localized spots..
