Q47 / 170 · Manipal (MET) 2021 · Chemistry

When the more electropositive metal displace less electropositive metals form their salt solution this process is called:

  • A
    auto reduction
  • B
    electro reduction
  • Correct answer
    C
    hydrometallurgy
  • D
    none of these

Solution

When more electropositive metal displace less electropositive metals from their salt solution, this is reduction by precipitation and the process is called hydrometallurgy.

Hence, the correct answer is option: 'C'.
