Identify the correct statements from the following. (A) BeSO ₄ is soluble in water. (B) BeO is an amphoteric oxide. (C) CO can be obtained by heating CaCO ₃ at 1070-1270 K.
Options
- AA, B, C
- BA and B
- CA and C
- DB and C
Correct answer
B. A and B
Step-by-step solution
(A) BeSO ₄ is soluble in water due to higher hydration energy of Be ²⁺ . It overcomes the lattice energy fâctors making BeSO ₄ soluble in water. The statement is correct. (B) BeO is amphoteric oxide as it can react with both acid and base, thus acting as basic and acidic respectively. The given statement is thus correct. (C) CO can be obtained by heating CaCO ₃ at 1070-1270 ~K is a incorrect statement. CaCO ₃ CaC + CO ₂ The correct statements are only A and B.
