Question

Pure metals do not corrode.

• A. True
• B. False

Answer 1

The correct option is A True

• Pure metals do not corrode.
• In impure metals, the presence of other metals tends to increase the rate of corrosion.
• To prevent corrosion alloy can be prepared.
• Alloy - It is a substance formed from the combination of two or more metals and from combinations of metals and other elements.
• Example - $\mathrm{Iron}\left(\mathrm{Fe}\right)$can be prevented from corrosion by alloying $$iron with chromium$\left(\mathrm{Cr}\right)$ and nickel$\left(\mathrm{Ni}\right)$.
• Stainless steel can be prepared with 74% iron, Chromium 18%, and Nickel 8% which is corrosion resistant and used to make knives, utensils, cutlery, etc.

Therefore, the given statement is true.
