Identify the correct statements:
Identify the correct statements:
Show Hint
Be compounds often show amphoteric behavior. CaCO\(_3\) decomposition yields CO\(_2\), not CO.
Updated On: May 20, 2025
- BeSO\(_4\) is soluble in water.
- BeO is an amphoteric oxide.
- CO can be obtained by heating CaCO\(_3\) at 1070–1270 K.
- a, b, c
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
- (a) BeSO\(_4\) is soluble in water due to the small ionic size of Be\(^{2+}\) and high hydration enthalpy.
- (b) BeO is amphoteric, reacting with both acids and bases.
- (c) Incorrect: Heating CaCO\(_3\) produces CO\(_2\), not CO: \[ \text{CaCO}_3 \xrightarrow{heat} \text{CaO} + \text{CO}_2 \]
- (b) BeO is amphoteric, reacting with both acids and bases.
- (c) Incorrect: Heating CaCO\(_3\) produces CO\(_2\), not CO: \[ \text{CaCO}_3 \xrightarrow{heat} \text{CaO} + \text{CO}_2 \]
