Preparation and properties of sodium hydroxide solution

Article no: P7159000
Principle

Caustic soda solution can be prepared on the basis of sodium hydroxide and water. During this process, energy is released in the form of heat. The sodium hydroxide solution thus produced shows the typical properties of an alkaline solution.

Tasks

Prepare a caustic soda solution and study its properties.

 

Benefits

  • Easy teaching and efficient learning by using interactive experimentation PHYWE-Software
  • Experiment is part of a complete solution set with experiments for the topic acids, alkalis and salts matched with international curriculum: all topics are covered
