Question
Which of the following is the strongest oxidising agent
 
Options:
A .  BrO−3/Br2+, E0=+1.50
B .  Fe3+/Fe2+, E0=+0.76
C .  MnO−4/Mn2+, E0=+1.52
D .  Cr2O2−7/Cr3+, E0=+1.33
Answer: Option C
:
C
Reduction potential is a measure of the tendency of a chemical species to acquire electrons and thereby be reduced. Measured in volts (V), or millivolts (mV) - each species has its own intrinsic reduction potential. The more positive the potential, the greater the species' affinity for electrons and tendency to be reduced. Hence - among the given options - MnO4is strongest oxidising agent. In other words -MnO4 has the best affinity to get reduced and thus has the greatest ability to oxidise.
