Which one of the following is most likely a mismatch?

Options

  1. AZinc-Liquation
  2. BCopper-Electrolysis
  3. CNickel-Mond process
  4. DTitanium-van Arkel Method

Correct answer

A. Zinc-Liquation

Step-by-step solution

Mond's process involves the combination of carbon monoxide with nickel readily and reversibly and gives nickel tetracarbonyl. This process is used to extract and purify nickel. The Van Arkel technique is used to refine Zirconium or Titanium. Impurities found in Zirconium or Titanium in the form of nitrogen and oxygen are eliminated using this technique. Copper is purified by electrolysis. Electricity is passed through solutions containing copper compounds, such as copper sulphate. The anode (positive electrode
