Given below are two statements:
Statement I: H₂O₂ can act as both oxidizing and reducing agent in basic medium.
Statement II: In the hydrogen economy, the energy is transmitted in the form of dihydrogen.
In the light of the above statements, choose the correct answer from the options given below:
Statement I: H₂O₂ can act as both oxidizing and reducing agent in basic medium.
Statement II: In the hydrogen economy, the energy is transmitted in the form of dihydrogen.
In the light of the above statements, choose the correct answer from the options given below:
- (A)Both statement I and statement II are false
- (B)Statement I is false but statement II is true
- (C)Both statement I and statement II are true✓ Correct
- (D)Statement I is true but statement II is false
Answer: (C)
Solution
In alkaline solution hydrogen peroxide oxidises iron(II) to iron(III) and manganese(II) to manganese(IV), itself passing to hydroxide ion, and it reduces permanganate to manganese dioxide and iodine to iodide, itself passing to dioxygen. Both roles are open to it in the same medium, so Statement I is true.
The hydrogen economy stores energy chemically as dihydrogen produced from water, moves that dihydrogen through pipelines or cylinders, and releases the energy in a fuel cell or burner at the point of use, so the energy is indeed transmitted in the form of dihydrogen. Statement II is true.
Both Statement I and Statement II are true.
