Unknown Principle Hydrochloric acid, which belongs to the group of strong acides, can be obtained from common salt. During this process hydrogen chloride gases are released. The presence of hydrogen chloride (in a solution) can be indicated with the aid of silver nitrate. In this experiment students prepare hydrochloric acid on the basis of common salt (sodium chloride) and study its properties. Learning objectives - Preparation and properties of hydrochloric acid
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
