What to Focus On

  • Hydrogen chloride gas is heavier than air and highly soluble in water.
  • Dry HCl gas is not acidic; acidity appears only in water.
  • Hydrochloric acid is a strong monobasic acid.
  • Ammonia is lighter than air and highly soluble in water.
  • Quick lime is the drying agent for ammonia.
  • Ammonia cannot be collected over water.
  • Pure nitric acid is colourless; commercial acid may be yellowish brown due to dissolved NO2.
  • Nitric acid is a strong monobasic acid and powerful oxidising agent.
  • Laboratory preparation uses KNO3 or NaNO3 with conc. H2SO4 at 150-200°C.

Common Mistakes to Avoid

Hydrogen chloride gas is acidic by itself and turns dry blue litmus red.

Ammonia gas can be collected over water because it is a gas.

Hydrogen chloride gas can be dried using quick lime or phosphorus pentoxide like many other gases.

Memory Tips
