Why do white fumes appear around the bottle of Aluminium chloride when kept for some time

Asked by shaktidevgun | 2nd Dec, 2015, 07:19: PM

Expert Answer:

  • White fumes are due to the presence of HCl gas.
  • Anhydrous aluminium chloride is hydrolysed partly with the moisture in the atmosphere to give HCl gas. 
  • This HCl combines with the moisture in the air and appears white in colour.
         AlCl3 + 3H2O → Al(OH)3 + 3HCl (white fumes)
