Disproportionation

Question 1

Disproportionation reaction definition

Answer 1

A redox reaction where a single atom or ion is oxidised and reduced at the same time in the same reaction

Question 2

Chlorine disproportion reaction with water

Answer 2

Cl2 (aq)+ H2O (l) -> HClO (aq) + HCl (aq)
0 +1 -1
Chlorine goes from 0 to positive 1 and negative 1

Question 3

Disproportionation reaction chlorine with sodium hydroxide

Answer 3

Cl2 (aq) + 2NaOH (aq) -> NaClO (aq) + NaCl (aq) + H2O (aq)

Chlorine goes from 0 to +1 and -1

The sodium hydroxide in this reaction (2NaOH) must be dilute and cold for this reaction to work
