Consider the following standard electrode potentials (Eo in volts) in aqueous solution :
Based on these data, which of the following statements is correct ?
| Element | M3+ /M | M+ /M |
|---|---|---|
| A1 | -1.66 | + 0.55 |
| T1 | +1.26 | - 0.34 |
Based on these data, which of the following statements is correct ?
Multiple Choice Options
- A T13+ is more stable than A13+
- B T1+ is more stable than A13+
- C A1+ is more stable than A13+
- D T1 + is more stable than A1+
Step-by-Step Verified Solution
The standard electrode potential E0 for M+/M become negative for Tl which indicates that Tl+ is more stable than Al+.
This can also be be explained by inert pair effect. The atoms of this group have an outer electronic configuration of s2p1. The two s electrons of Tl do not participate in bonding due to poor shielding of d electrons.
