Standard electrode potential values, 
for 
is -1.66 V and that of 
is +1.26 V
. On the basis of this data, which of the following statement is wrong?
A
Al has high tendency to form 
ions.
ions. B
is not only unstable in solution but is a powerful oxidising agent also. C
is more stable in solution than 
. D
Aluminium is less electropositive than thallium.
Text Solution
Verified by ExpertsThe correct answer is:
D
The negative values of 
for 
suggest that Al has strong tendency to form 
ions. On the other hand, positive value of 
for 
suggest that Tl does not have high tendency to form 
ions. Since, Al can form 
ions more easily than Tl does to form 
ions. Therefore, Al is more electropositive than Tl .
