How does galvanisation protect iron or steel from corrosion?
In a fair test designed to investigate the effect of salt concentration on the rusting of iron nails, which of the following would be the independent variable?
Metals generally corrode faster in warm, humid climates because the rate of chemical reactions is higher and the humidity __________.
In many metals like aluminium, simple oxidation is self-limiting because the oxide layer is __________, whereas the rust on iron is porous and flaky, allowing further deterioration.
In the context of ship maintenance, why are zinc blocks (sacrificial anodes) preferred over simply painting the hull when the ship is frequently in contact with harsh saltwater?
In environments affected by acid rain, which cathodic reduction reaction is primarily responsible for the accelerated deterioration of the metal?
What is the primary reason that stainless steel is highly resistant to corrosion?
Which of the following statements correctly describes the difference between simple oxidation and corrosion?
Which of the following represents the cathodic reaction during the rusting of iron in a neutral environment?
