The standard reduction potential at 25oC of Li+/Li, Ba2+/Ba, Na+/Na and Mg2+/Mg are -3.05, -2.73, -2.71 and -2.37 repectively. Which one of the following is he strongest oxiziding agent ?
Na+
Li+
Ba2+
Mg2+
As we have learnt,
Standard reduction potential -
It measure the tendency of a chemical species to acquire electrons and there by be reduced. It is measured in volts or mv.
-
Mg2+ has the highest reduction potential so its the strongest oxidizing agent.
Option 1)
Na+
Option 2)
Li+
Option 3)
Ba2+
Option 4)
Mg2+
