The standard electrode potential (in V) values for Al ³⁺ / Al , Tl ³⁺ / T 1 are respectively

Options

A-1.66,-1.26
B+1.66,+1.26
C-1.66,+1.26
D+1.66,-1.26

Correct answer

C. -1.66,+1.26

Step-by-step solution

( Al ³⁺ is much more stable than Al and due to electropositive nature, the standard reduction potential of Al ³⁺ / Al is negative. Tl is not as electropositive as Al and therefore Tl ³⁺ can easily be reduced to Tl because of which its SEP value is positive.
