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 Lithium has the lowest electrode potential indicating
that lithium ion is the weakest oxidising agent while lithium metal is
the most powerful reducing agent in an aqueous solution It may be
seen that as we go from top to bottom in Table 2 1 the standard
electrode potential decreases and with this, decreases the oxidising
power of the species on the left and increases the reducing power of
the species on the right hand side of the reaction
