What kind of reaction that chlorine undergoes with aqueous alkali solution ? 

Text Solution

Verified by Experts

Chlorine reacts with aqueous caustic soda in different conditions. `Cl_2 + 2NaOH overset("cold")(rarr)NaCl + NaOCl + H_2O`
`3Cl_2 + 6NaOH overset("hot")(rarr)5NaCl + NaClO_3 + 3H_2O`
Chlorine undergoes disproportionation with alkali. Chlorine is reduced to chloride and simultaneously oxidised to hypochlorite or chlorate.
