1.	The standard reduction potential at 298K for the following half reaction are given against each `Zn^(2+)(aq)+2e^(-)hArrZn(s)" "-0.762` `Cr^(3+)(aq)+2e^(-)hArrCr(s)" "-0.740` `2H^(+)(aq)+2e^(-)hArrH_(2)(g)" "0.000` `Fe^(3+)(aq)+2e^(-)hArrFe^(2+)(aq)" "0.770` which is the strongest reducing agentA. Zn(s)B. Cr(s)C. `H_(2)(g)`D. `Fe^(2+)(aq)`
Answer» Correct Answer - A More negative is the reduction potential, higher will be the reducing property, i.e., the power to give up electrons.
