Reducing Agent Tendency
Consider the following reduction processes :
Al
3+
+ 3e
–
→ Al(s), E
o
= –1.66 V
Fe
3+
+ e
–
→ Fe
2+
, E
o
= +0.77 V
Co
3+
+ e
–
→ Co
2+
, E
o
= +1.81 V
Cr
3+
+ 3e
–
→ Cr(s), E
o
= –0.74 V
The tendency to act as reducing agent decreases in the order :
SELECT ONE OPTION
A
Al > Cr > Fe
2+
> Co
2+
B
Al > Fe
2+
> Cr > Co
2+
C
Al > Cr > Co
2+
> Fe
2+
D
Cr > Fe
2+
> Al > Co
2+
