Fe^(2+)//Fe के लिए E^(+) = -0.44 V, Cu//...

`Fe^(2+)//Fe` के लिए `E^(+) = -0.44 V, Cu//Cu^(2+)` के लिए `E^(@) = 0.34 V`, है, तब सेल में-

A

`Cu^(2+), Fe` को ऑक्सीकृत करता है

B

`Fe^(2+), Cu` को ऑक्सीकृत करता है

C

`Cu, Fe^(2+)` को अपचयित करता है

D

`Fe, Cu^(2+)` को अपचयित करता है

Text Solution

Verified by Experts

The correct Answer is:
D

अपचयन विभव `Cu^(2+)//Cu = 0.34V` और `Fe^(2+)//Fe = -0.44V`,
इस प्रकार `Fe + Cu^(2+) to Fe^(2+) + Cu` के लिए `E^(@), 0.78` है, इसलिए `Fe, Cu^(2+)` को अपचयित करता है।
