Identify the correct order of increasing reducing strength of metals from following.
Options
- AAg < Ni < Mg < Li
- BLi < Mg < Ni < Ag
- CMg < Ni < Ag < Li
- DNi < Ag < Li < Mg
Correct answer
A. Ag < Ni < Mg < Li
Step-by-step solution
Reducing strength of a metal depends on its tendency to lose electrons, which is inversely proportional to its standard reduction potential ( E^ ). A lower (more negative) standard reduction potential indicates a stronger reducing agent. The standard reduction potentials ( E^ ) for the given metals are: E^ _ Li ⁺ / Li = -3.05 V E^ _ Mg ²⁺ / Mg = -2.36 V E^ _ Ni ²⁺ / Ni = -0.25 V E^ _ Ag ⁺ / Ag = +0.80 V Since the reduction potential increases in the order Li Thus, the correct order of increasing reducing strength i
