Question
The oxide that gives H O most readily on treatment with H O is 2 2 2 2 2 2 2 2 2 2 2 4 2 2 2 2 2 2 2 4 2 2 2 2 (A) PbO (B) Na O (C) SnO (D) BaO ⋅8H O
Answer: B) NA O
💡 Solution & Explanation
1. PbO + 2H O → Pb(OH) 2. Na O + 2H O → 2NaOH + H O This reaction is possible at room temperature 3. SnO + 2H O → Sn(OH) 4. Acidified BaO .8H O gives H O after evaporation
