Science teacher announced to go to a picnic. The picnic spot is the Nallamala forest. Then Ajay got some doubts in him. He wants to get answers for his doubts. What questions he might have asked his teacher about the Nallamala forest?

Redox reactions play a pivotal role I chemistry and bilogy . The values of standard redox potential (E^(@)) of two half - cell reaction decided which way the reaction is expected to proceed. A simple example is a Daniel cell in which zinc goes into solution and copper get deposited. Given below are a set of half 0 cell reactions ( acidic medium ) along with their E^(@) values ( with respect to normal hydrogen electrode ) Using this data : I_2 + 2e^(-) to 2I^(-) E^(@) = 0.54 , Cl_2 + 2e^(-) to 2Cl^(-) " "E=1.36V Mn^(3+) + e^(-) to Mn^(2+) E^(@) = 1.50 , Fe^(3+) + e^(-) to Fe^(2+) E = 0.77V O_2 +4H^(+) + 4e^(-) to 2H_2O" " E^(@) = 1.23 , While Fe^(3+) is stable , Mn^(3+) is not stable in acid solution because :
