3. CaCl₂ to dry the gas

Explanation:

  • The guard tube contains anhydrous calcium chloride.
  • During Humid temperature, the gas produced usually has some vapour diffused within it .
  • When the gas is passed through the guard tube, the calcium chloride absorbs water molecules.
  • It reduces the moisture content of the gas.
