What is the unique behaviour of Cu with regard to its standard electrode potential (Eo)?

Options

  1. ACu has a negative Eo.
  2. BCu has a positive Eo.
  3. CCu's E_ is zero.
  4. DCu's E_ depends on the temperature.

Correct answer

B. Cu has a positive Eo.

Step-by-step solution

The unique behaviour of Cu, having a positive E_, accounts for its inability to liberate H 2 from acids.
