Identify the correct statement from the following :
(1) Blister copper has blistered appearance due to evolution of CO2.
(2) Vapour phase refining is carried out for Nickel by Van Arkel method.
(3) Pig iron can be moulded into a variety of shapes.
(4) Wrought iron is impure iron with 4% carbon.

Correct option: (3)

Explanation:

  • Because of the evolution of SO_2, not CO_2, blister copper has a blistered appearance.
  • The Van Arkel method is used to obtain ultra-pure Titanium through vapor phase refining.
  • The iron produced in a blast furnace contains about 4% carbon and a variety of impurities in smaller quantities (e.g., S, P, Si, Mn). Pig iron is the term for this. It can be molded into a number of different shapes. This is the only statement that is correct.
  • Wrought iron is a type of impure iron that contains 0.1 percent carbon.
