The correct statement among the following is:
Options
- AB i 5 + salts act as good oxidising agents
- BS n 2 + salts act as good Reducing agents
- CT l 3 + salts act as good oxidising agents
- DAll of these
Correct answer
D. All of these
Step-by-step solution
S n 4 + > S n 2 + (order of stability) ∴ S n 2 + act as good Reducing agent S n 2 + → S n 4 + + 2 e θ + 2 + 4 Also, B i 3 + > B i 5 + T l + > T l 3 + order of stability (Inert pair effect) ∴ B i 5 + + 2 e → B i 3 + + 5 + 3 T l 3 + + 2 e Θ → T l + + 3 + 1 while in a group atomic size increases There B i 5 + and T i 3 + act as good oxidising agents
