In aqueous solution `Cr^(2+)` is stronger reducing agent than `Fe^(2+)`. This is because

A stronger reducing agent is

A stronger reducing agent is

Copper is a stronger reducing agent than silver.

F_(2) is a stronger oxidising agent than Cl_(2)

F_(2) is a stronger oxidising agent than Cl_(2)

Lithium has a much higher ionisation energy than cesium but in aqueous solution Li is a morepowerful reducing agent than cesium because
