Which one is known as a fusion mixture?
Fusion mixture is the mixture of potassium carbonate and sodium carbonate mixture.
The mixture is fused with the organic compounds and various tests for the group analysis are done using this mixture. It is very much effective for the qualitative analysis for the organic compounds for different groups.
Since and
belong to the first group i.e. the alkali metals, which are the most reactive elements in the periodic table. They have the potential to break the covalent bonds formed between the carbon atom and other atoms like nitrogen, oxygen, sulphur, halides etc., and after breaking these covalent bonds, ionic bonds are introduced between the respective atoms and the
or
in the fusion mixture.
Like with the halides they form the halides and with sulphur they form the sulphides etc.
So, a mixture of sodium carbonate and potassium carbonate is called the fusion mixture.
