Why do metals corrode?
Metals corrode due to a chemical reaction with their environment, typically with oxygen or moisture. This reaction causes the metal to form a more stable compound, such as rust, which weakens the metal's structure over time. Control measures such as coating or alloying metals can help prevent corrosion.
Why do some metal corrode while others do not?
All metals corrode under the right conditions only some more easily then others. as it turn out the metals that corrode most easily are usually also the most abundant.
If steel and copper were in contact in an electrolyte which would corrode?
In this scenario, copper would corrode because it is lower in the galvanic series compared to steel. When two dissimilar metals are in contact in an electrolyte, the metal higher in the galvanic series (steel) acts as the anode and corrodes, while the metal lower in the series (copper) acts as the cathode and is protected.
Can metal used to provide sacrificial corrosion?
Yes, a more reactive metal can be used as a sacrificial anode to protect a less reactive metal from corrosion. The sacrificial metal will corrode instead of the protected metal, sacrificing itself to prevent corrosion damage. Common sacrificial anodes are made of zinc or magnesium.
Which is more stable pure metal or its ore?
Pure metal is more stable than its ore because ores are compounds that contain the metal combined with other elements. In order to obtain pure metal from an ore, the ore needs to undergo chemical processes like reduction or electrolysis. This means that pure metal has a higher energy state compared to ores, making it more stable.
Can metal which is inside window glass corrode more over time?
If the window is not perfectly sealed (and it isn't likely to be), then it is possible for the metal to corrode due to exposure to oxygen and water.
Why do metal corrode more quickly near the sea?
Salt water is corrosive. And there is more moisture in the air.

When more valence electrons of metal are shared it's melting point tends to be?
When more valence electrons of a metal are shared, the metallic bonding becomes stronger, leading to a higher melting point. This is because the increased delocalization of electrons throughout the metal lattice requires more energy to break the bonds in order to melt the metal.
If steel and copper were in contact in an electrolyte which would corrode?
In this scenario, copper would corrode because it is lower in the galvanic series compared to steel. When two dissimilar metals are in contact in an electrolyte, the metal higher in the galvanic series (steel) acts as the anode and corrodes, while the metal lower in the series (copper) acts as the cathode and is protected.
Which of the metals Zn Fe and Ag which will corrode the easiest?
Zinc will corrode the easiest among zinc (Zn), iron (Fe), and silver (Ag). This is because zinc is more reactive than iron and silver, making it more prone to oxidation and corrosion in the presence of moisture and oxygen.
Does gold corrode more easily thans silver?
As i rememeber gold do not corrode at all.
Which will corrode more quickly a pipe that carries hot water or one that carries cold water?
A pipe carrying hot water will generally corrode more quickly than one carrying cold water. The higher temperature of the hot water can accelerate the corrosion process by making the metal more reactive and causing it to deteriorate faster over time.
Why does metals corrode more quickly near the sea?
Because some metals are reactive and corrode in sea water
