Manufacture of Bleaching Powder & Soap (55x90cm)

The “Manufacture of Bleaching Powder & Soap” (55x90 cm) educational chart presents clear, stepwise diagrams and explanations illustrating both the industrial synthesis processes for bleaching powder and soap, designed for chemistry classrooms and industrial training.​

Key Features and Processes Shown

Printed in multicolor on sturdy, laminated 55x90 cm paper, this chart clearly labels and sequences every major step for both bleaching powder and soap production.​

The bleaching powder section typically depicts the Hasenclever or Bachmann’s plant, showing:

Introduction of slaked lime (calcium hydroxide) and chlorine gas into a tower with shelves or cylinders.

Collection of bleaching powder at the tower's base and removal of waste gases from the top.​​

The soap manufacturing part usually illustrates the saponification process:

Fats/oils react with sodium hydroxide (lye) forming soap and glycerol.​

Describes stages such as lye separation, washing columns, and subsequent purification.​

Educational Utility

Each stage is visually coded for easy comprehension, with concise text describing reactants, products, industrial equipment, and by-products.

Useful for teaching fundamental concepts in industrial chemistry, chemical engineering, and everyday applications of chemical reactions.​

Highlights safety, utility, and societal impact of bleaching powder (for water treatment, bleaching fabrics) and soap (for cleaning, hygiene).​

This poster is ideal for chemistry labs, science classrooms, or technical training centers, making industrial chemical processes accessible and engaging to learners.
