The standard electrode potential (in V) values for \(\mathrm{Al}^{3+}\) / \(\mathrm{Al}, \mathrm{Tl}^{3+} / \mathrm{T} 1\) are respectively
- A \(-1.66,-1.26\)
- B \(+1.66,+1.26\)
- C \(-1.66,+1.26\)
- D \(+1.66,-1.26\)
Answer & Solution
Correct Answer
(C) \(-1.66,+1.26\)
Step-by-step Solution
Detailed explanation
(\(\mathrm{Al}^{3+}\) is much more stable than \(\mathrm{Al}\) and due to electropositive nature, the standard reduction potential of \(\mathrm{Al}^{3+} / \mathrm{Al}\) is negative. \(\mathrm{Tl}\) is not as electropositive as \(\mathrm{Al}\) and therefore \(\mathrm{Tl}^{3+}\)…
