Principle

The oxidation of non-decomposable organic substances and the detection of the carbon as carbon dioxide was carried out long ago by Justus von Liebig. When urea is heated above its melting point, biuret is formed:
2 CO(NH2)2 → H2N-CO-NH-CO-NH2 + NH3

Learning objectives

  • Carbon cannot always be detected directly in organic substances.
  • ln such cases, it can be oxidized to carbon dioxide with copper(ll) oxide, carbon dioxide can then be detected with limewater.

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 Organic Chemistry matched with international curriculum: all topics are covered
