Why a pure metal half immersed vertically in water starts corroding?
When a pure metal is half-immersed in water, an electrochemical cell is formed due to the difference in oxygen concentration between the exposed and immersed parts. This sets up a potential difference, leading to the flow of electrons and causing corrosion on the exposed part of the metal. The process is known as galvanic corrosion and results in the degradation of the metal over time.
Why the iron pot developed some holes in it when copper sulphate is kept immersed in it?
The reaction between iron and copper sulfate leads to the formation of iron(II) sulfate and elemental copper. As a result, the iron pot develops holes due to the corrosion caused by the chemical reaction between the iron in the pot and the copper sulfate solution. This process is known as galvanic corrosion.
What are three ways to protect metal from corrosion and how do they work to stop it?
Here are four ways (adapted from the related link): Corrosion control Protective coatings: Most widely used corrosion control technique. Protective coatings protect metal from corrosion by separating the surfaces that are susceptible to corrosion from the factors in the environment which cause corrosion to occur. Cathodic protection: interferes with the natural action of the electrochemical cells that are responsible for corrosion. Cathodic protection can be effectively applied to control corrosion of surfaces that are immersed in water or exposed to soil. Corrosion inhibitor: Uses one or more of these mechanisms: Adsorption as a thin film on the surface of a corroding material; inducing formation of a thick corrosion product; forming a passive film on the metal surface; changing characteristics of the environment either by producing protective precipitates or by removing or inactivating an aggressive constituent.
What part of speech is corrosion?
Corrosion is a noun.
Is copper resistant to corrosion?
Yes, copper is resistant to corrosion.
What is galvic corrosion?
Galvanic corrosion is an electrochemical process in which one metal corrodes preferentially when in electrical contact with a different type of metal and both metals are immersed in an electrolyte.

Is a liquid immersed transformer the same as oil immersed transformer?
Liquid immersed transformers are typically immersed in what?
Is there anything special you need to do to clean your camera and stop corrosion after it was accidentally immersed in salt water?
Yes you should not expose your camera lens to direct sunlight for a long time when you are cleaning it.
What is galvanic insulation?
galvanic insulation is when two different metal materials are electrically isolated to prevent galvanic corrosion. Galvanic corrosion is similar to the reaction that takes place in an electric battery cell. Two materials, an anode and a cathode, immersed in an electrolyte produce a voltage that causes metal ions from the anode to move to the cathode. This is a desired effect in a battery since it allows electricity to charge and discharge. However, the galvanic reaction causes the anode to gradually corrode and when corrosion is not desirable, the materials must be insulated. For example, when immersed in water, aluminum acts as an anode for chromium, which can cause aluminum parts to corrode when it rains, unless they are insulated. Both of these materials are used in some products, such as automobiles, for structural and ornamental purposes, and corrosion is generally not desired. Therefore they must be galvanically insulated to prevent corrosion.
