A solution contains Pb^(2+) and Fe^(2+) ...

A solution contains `Pb^(2+)` and `Fe^(2+)` ions. To it some quantity of Fe and Pb is added. Then
[ `E_(Fe^(2+)//Fe)^@=0.44` V `E_(pd^(2+)//pd)=0.126` V]

A

concentration of `Pb^(2+)` ions will remain unaffected

B

concentration of `Pb^(2+)` ions will increase

C

concentration of `Fe^(2+)` ions will increase

D

concentration of `Fe^(2+)` ions will decrease.

Text Solution

Verified by Experts

The correct Answer is:
C

The reaction that occurs will be
`Pb^(2+)+FetoFe^(2+)+Pd`
On adding Fe and Pb, Fe will be consumed to increase the concentration of `Fe^(2+)` .

A solution contains Fe^(2+), Fe^(3+) and T^(-) ions. This solution was treated with iodine at 35^(@)C. E^(@) for Fe^(3+), Fe^(2+) is 0.77 V and E^(@) for I_(2)//2I^(-) = 0.536 V. The favourable redox reaction is:

Aerial oxidation gradually changes Fe^(2+) ions to Fe^(3+) ions. Which of the following should be added to Fe^(2+) ions to prevent this from happening? Use E_(Fe^(3+)//Fe^(2-))^(@) = +0.771 V, E_(Cu^(2+)//Cu)^(@) = +0.34 V. E_(Mg^(2+)//Mg = -2.37 V
