The standard reduction potentials (in V) of a few metal ion/metal electrodes are given below. The reducing strength of the metals follows the order.

Options

  1. AAg > Cu > Pb > Cr
  2. BCr > Pb > Cu > Ag
  3. CPb > Cr > Ag > Cu
  4. DCr > Ag > Cu > Pb

Correct answer

B. Cr > Pb > Cu > Ag

Step-by-step solution

Which have low value of reduction potential is a good reducing agent. Cr > Pb > Cu > Ag
