प्रश्न
Give reason.
Ga3+ salts are better reducing agents while Tl3+ salts are the better oxidizing agent.
उत्तर
- Both gallium (Ga) and thallium (Tl) belong to group 13.
- Ga is a lighter element compared to thallium Tl. Therefore, its +3 oxidation state is stable. Thus, Ga+ loses two electrons and gets oxidized to Ga3+. Hence, Ga+ salts are better-reducing agents.
- Thallium is a heavy element. Therefore, due to the inert pair effect, Tl forms stable compounds in +1 oxidation state. Thus, Tl3+ salts get easily reduced to Tl1+ by accepting two electrons. Hence, Tl3+ salts are the better oxidizing agent.
