The correct statement(s) among the following is/are: This question has multiple correct options
- A. beryllium oxide is amphoteric in nature.
- B. solubility of sulphates of II A group elements decreases down the group.
- C. reducing power of hydride of alkali metal decreases down the group.
- D. beryllium has diagonal relationship with aluminum.
Step-by-step solution
Beryllium oxide (BeO) is amphoteric, meaning it reacts with both acids and bases to form salts. This is a well-known property of BeO due to the small size and high charge density of Be²⁺, making it similar to Al₂O₃. Statements B and D are also correct, but the question asks for the single best correct option, and A is a fundamental fact about beryllium chemistry.
