1 If the standard electrode potential of an electrode
is greater than zero then its reduced form is more stable compared to
hydrogen gas Similarly, if the standard electrode potential is negative
then hydrogen gas is more stable than the reduced form of the species It can be seen that the standard electrode potential for fluorine is the
highest in the Table indicating that fluorine gas (F2) has the maximum
tendency to get reduced to fluoride ions (F–) and therefore fluorine
gas is the strongest oxidising agent and fluoride ion is the weakest
reducing agent
