SUMMARY

To prepare a 25% Aluminum Chloride Solution, it is recommended to start with aluminum chlorohydrate rather than attempting to produce aluminum chloride (AlCl3) through the reaction of aluminum with hydrochloric acid. The latter method is hazardous due to the production of hydrogen gas and hot HCl fumes. Using aluminum chlorohydrate simplifies the process and enhances safety while achieving the desired concentration.

PREREQUISITES
  • Understanding of chemical reactions involving aluminum and hydrochloric acid
  • Knowledge of aluminum chlorohydrate properties
  • Familiarity with solution preparation techniques
  • Basic safety protocols for handling corrosive substances
NEXT STEPS
  • Research the properties and applications of aluminum chlorohydrate
  • Learn about the safe handling and storage of hydrochloric acid
  • Study the process of preparing concentrated solutions in a laboratory setting
  • Investigate alternative methods for producing aluminum chloride safely
USEFUL FOR

Chemistry students, laboratory technicians, and professionals involved in chemical preparation and handling who require knowledge on producing aluminum chloride solutions safely.

Does anyone know a good method of producing Aluminum Chloride in liquid form? I need to prepare a 25% Aluminum Chloride Solution for my presentation. Any help would be greatly appreciated.

You can do that by dissolving aluminum in hydrochloric acid and boiling off the HCL. The reaction produces hydrogen, hot HCl fumes and may spit as the liquid is boiled to dryness. Pretty dangerous stuff! It is much easier and safer to buy the aluminum chloride as aluminum chlorohydrate.

Aluminum chloride (AlCl3, anhydrous) will react with water aggressively to form aluminum chlorohydrate and hydrochloric acid. Since you intend to make up an aqueous solution of this, you could start with aluminum chlorohydrate.
