Answer» Correct Answer - A (a) More negative (or less positive) the value of reduction potential, stranger will be the reducing agent. Thus `l^(-)` is the strongest reducing agent. More positive is the values of reduction potential, stronger will be the oxidising agent. Thus, `F_(2)` is the strongest oxidising agent. |
