Select CORRECT statement.

Options:(select one or more)

Answer:
B, C
Solution:

Identify 'X': Reaction of Ca(OH)₂ with limited CO₂ forms calcium carbonate, so 'X' is CaCO₃.

Statement (B) is CORRECT: Calcium carbonate (CaCO₃) is a well-known white precipitate (ppt).

Statement (C) is CORRECT: Passing excess CO₂ converts insoluble CaCO₃ into soluble calcium bicarbonate [Ca(HCO₃)₂].

Incorrect Options: (A) is wrong because CaCO₃ is insoluble, and (D) is wrong because it readily dissolves in dilute HCl to form CaCl₂ and CO₂ gas.
