MCQ
Quicklime is not used to dry HCl gas because:
  • A
    Acidic
  • B
    Alkaline
  • C
    Neutral
  • D
    None of these
✓

Answer

B. Alkaline
Explanation: Quicklime is a basic substance (alkaline) and reacts with acidic gases like hydrogen chloride (HCl). When quicklime reacts with $HCl _{\text {, }}$ it can form calcium chloride and water, thus not effectively drying the gas but rather contributing to unwanted chemical reactions.
