Which of the following statements are correct concerning redox properties ?
1. A metal M for which `E^(@)` for the half reaction `M^(n+)+"ne"^(-)=M`, is very negative will be a good reducing agent
2. The oxidizing power of the halogens decreases from chlorine to iodine
3. The reducing power of hydrogen halides increases from hydrogen chloride to hydrogen iodide.

A

1, 2 and 3

B

1 and 2

C

1 only

D

2 and 3 only

Text Solution

Verified by Experts

The correct Answer is:
A
I. Reducing character `propto 1/"reduction potentials"`
II. Oxidising power of halogens decreases from `F_(2)" to "I_(2)` because their reduction potentials decreases from fluorine to iodine.
III. The reducing power of hydrogen halides increases from hydrogen chloride to hydrogen iodide since, the stability of the H-X bond decreases in the same order. Hence, all statements are correct.

Which of the following statements are correct? Fuel cells are galvanic cells in which the chemical energy of fuel is directly converted into electrical energy. Type of fuel cell is a hydrogen - oxygen fuel cell. It consists of two electrodes made up of two porous graphite impregnated with a catalyst (platinum, silver, or metal oxide). The electrodes are placed in aqueous solution of NaOH. Oxygen nad hydrogen are continuously fed into the cell. Hydrogen gets oxidized to H^(oplus) which is neutralized by overset(Θ)(OH) , ie., anodic reaction. H_(2) hArr 2H^(oplus) + 2e^(-) 2H^(oplus) + 2 overset(Θ)(OH) hArr 2H_(2)O H_(2) + 2 overset(Θ)(OH) hArr 2H_(2)O + 2e^(-) At cathode, O_(2) gets reduced to overset(Θ)(OH) i.e., O_(2) + 2H_(2)O + 4e^(-) hArr overset(Θ)(4)OH Hence, the net reaction is 2H_(2) + O_(2) hArr 2H_(2)O The overall reaction has Delta H= -285.6kJ mol^(-1) and Delta G= -237.4kJ mol^(-1) " at " 25^(@)C A fuel cell is I.
