(1) Al+is unstable in solution because SRP of Al+/Al is positive hence, it will get reduced in solution. (2) Tl/Tl+=+0.34Tl/Tl3+=−1.26(SOP)(SOP) Since, SOP TI/TI > TI/T1 + Hence, TI will get oxidised to Tl+easily than Tl3+ (3) Since Al2/Al3+ has more SOP than Tl/Tl+it will be more electropositive (4) Since Tl3++2e−→Tl+;E=23×1.26+0.34=+2.04 Hence, Tl3+ is better oxidising agent not reducing agent
