Expert Answer:

  • Concentrated HCl solution is the concentrated mixture of HCl gas in water.
  • When the concentration of HCl gas in water becomes 22.2 % by weight, it forms a constant boiling mixture.
  • At this concentration if this solution is still heated, then water and HCl vaporise in the same proportion by weight.
  • Hence, beyond this limit, dilute HCl can not be concentrated.
