Principle

Air (oxygen) is needed for many reactions, e.g. for combustions.  In  this  experiment students determine whether air as a whole is required for combustion. This experiment shows that in combustion reactions only a part of the air is consumed. This result means that air must be a mixture of substances.

 

Learning objectives 

  • Air is a mixture of substances
  • Only a part of the air promotes combustion reactions

 

Benefits

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