Give the balanced equation for the reaction between chlorine with cold `NaOH` and hot `NaOH`.

Text Solution

Verified by Experts

(i) Reaction between chlorine with cold `NaOH:`
`Cl_(2)+H_(2)Orarr HCl+HOCl`
`HCl+NaOH rarr NaCl+H_(2)O`
`HOCl+NaOH rarr NaOCl+H_(2)O`
Overall reaction,
`Cl_(2)+underset("(cold)")(2NaOH)rarr underset("(Sodium hypochlorite)")(NaOCl)+underset("(Sodium chloride)")(NaCl+H_(2)O)`
Chlorine reacts with cold `NaOH` to give sodium chloride and sodium hypochlorite.
(ii) Reason between chlorine with hot `NaOH`:
`Cl_(2)+H_(2)Orarr HCl+HOCl`
`HCl+NaOH rarr NaCl+H_(2)O`
`HOCl+NaOH rarr NaOCl+H_(2)O`
`3NaOClrarr NaClO_(3)+2NaCl`
Overall reaction,
`3Cl_(2)+underset("(Hot)")(6NaOH)rarr underset("(Sodium chlorate)")(NaClO_(3))+underset("(Sodium chloride)")(5NaCl)+3H_(2)O`
Chlorine reacts with hot `NaOH` to give sodium chlorate and sodium chloride.
