Correct answer
DBoth statement I and statement II are true
Step-by-step explanation
Oxidising action in basic medium
2Fe2+ + H2O2 2Fe3+ + 2OH–
Reducing action in basic medium
I2 + H2O2 + 2OH– 2I– + 2H2O + O2
Advantage of hydrogen economy is that energy is transmitted in the form of dihydrogen and not as electric power
2Fe2+ + H2O2 2Fe3+ + 2OH–
Reducing action in basic medium
I2 + H2O2 + 2OH– 2I– + 2H2O + O2
Advantage of hydrogen economy is that energy is transmitted in the form of dihydrogen and not as electric power
