The reaction of calcium hydroxide with carbon dioxide to form calcium carbonate and water is an exam

Q: What is the correct answer for NCERT10?

The correct answer is C. The reaction Ca(OH)₂(aq) + CO₂(g) → CaCO₃(s) + H₂O(l) is described as part of whitewashing. While it produces two products, the context of the 'Do You Know?' box implies it's a step in a process related to combination, and it's a reaction where two substances combine to form new substances. More precisely, it's a reaction where a base reacts with an acidic oxide. However, within the context of the

FirstInTest · Accepted Answer

The reaction Ca(OH)₂(aq) + CO₂(g) → CaCO₃(s) + H₂O(l) is described as part of whitewashing. While it produces two products, the context of the 'Do You Know?' box implies it's a step in a process related to combination, and it's a reaction where two substances combine to form new substances. More precisely, it's a reaction where a base reacts with an acidic oxide. However, within the context of the chapter's classification, it's often taught alongside combination reactions or as a specific type of combination where a metal hydroxide reacts with a non-metal oxide. Given the options, it's not decomposition, displacement, or neutralization in the typical acid-base sense.
