Correct Answer - Option 2 : Lead
The correct answer is Lead.
Containers for carrying strong acids are made of Lead.
- Lead is a bluish-white lustrous metal.
- It is very soft, highly malleable, ductile, and a relatively poor conductor of electricity.
- It is very resistant to corrosion but tarnishes upon exposure to air.
- Lead isotopes are the end products of each of the three series of naturally occurring radioactive elements.
- The properties of lead that make it useful in a wide variety of applications are density, malleability, lubricity, flexibility, electrical conductivity, and coefficient of thermal expansion, all of which are quite high; and elastic modulus, elastic limit, strength, hardness, and melting point.
- Lead is still widely used for car batteries, pigments, ammunition, cable sheathing, weights for lifting, weight belts for diving, lead crystal glass, radiation protection, and in some solders.
- It is often used to store corrosive liquids.
