Che cos'è una reazione sproporzionata?
Risposta:
A reaction in which the same species is both oxidised and reduced.
Spiegazione:
A great example is chlorine mixing with water.
#Cl_2 + H_2O -> HCl + HClO#
Elemental chlorine (#Cl_2#) has a redox number of 0.
In #HCl#, it has a redox number of -1
E in #HClO# it has a redox number of +1
Therefore chlorine has been both oxidised and reduced in the same reaction. This is disproportionation.
