Question

Metal corrodes due to salts. State whether the given statement is true or false.
A. True
B. False

Answer 1

Hint: A metal is a substance that has a shiny look when freshly produced, polished, or shattered, and conducts electricity and heat reasonably effectively. Metals are either malleable or ductile (they may be hammered into thin sheets) (can be drawn into wires). Metals can be chemical elements like iron, alloys like stainless steel, or molecular compounds like polymeric sulfur nitride.

Complete answer:
Corrosion is a natural process that converts refined metals into chemically more stable compounds such as oxide, hydroxide, carbonate, or sulphide. It is the gradual deterioration of materials caused by chemical and/or electrochemical interactions with their environment over time. Corrosion occurs when a metal object is exposed to the environment and harsh weather. If the metal is iron, we call this transition rusting, and the weaker, flaky brown compound that develops is rust. As an electrolyte (a substance containing free ions that allows it to conduct electricity), salt solution causes iron to lose electrons more quickly, hastening the rusting process.
Adding salt to water speeds up the process. Because salt is such a strong electrolyte, it includes a lot of dissociated ions, which speeds up corrosion in salt water. By serving as an electrolyte, salt, or more specifically, salt solution, can speed up the rusting process by allowing the metal to lose electrons more quickly. Rusting is produced by the oxidation of metal atoms, which results in the loss of electrons and the formation of ions. As a result, adding salt or a salt solution (containing ions) to the rusting process accelerates the process by allowing electrons to flow more freely from iron to oxygen. The rule is that the more easily electrons flow, the faster the rusting process will be.

Hence option (A) is correct.

Note:
This refers to the electrochemical oxidation of metals in the presence of an oxidant such as oxygen or sulphates in the most basic sense. Electrochemical corrosion may be seen in the formation of iron oxides, which is known as rusting. This type of corrosion causes the original metal to produce oxides or salts, giving it a distinct orange hue. Other than metals, such as ceramics or polymers, corrosion can occur; however, the term "degradation" is more often used in this context. Corrosion degrades the use of materials and structures by reducing their strength, appearance, and liquid and gas permeability.
