Question

Which of the following statement is correct ?

• A. Bi⁵⁺ salts act as good oxidising agents
• B. Sn²⁺ salts act as good Reducing agents
• C. Tl³⁺ salts act as good oxidising agents
• D. All of these

Answer 1

Answer: (D)

All of these

Answer 2

Sn⁴⁺ > Sn²⁺ (order of stability)

\ Sn²⁺ act as good Reducing agent Sn²⁺ ® Sn⁴⁺ + 2e^q

(+2) (+4)

Also, $\left. \ \begin{aligned} & Bi^{3 +} > Bi^{5 +} \\ & Tl^{+} > Tl^{3 +} \end{aligned} \right\}$order of stability (Inert pair effect)

\ Bi⁵⁺ + 2e^Θ ® Bi³⁺

(+5) (+3)

Tl³⁺ + 2e^Q ® Tl⁺

(+3) (+1)

while in a group atomic size increases There Bi⁵⁺ and Ti³⁺ act as good oxidising agents
