$$\begin{array}{rl}& :{\mathrm{Cl}}_2+2\mathrm{NaOH}\text{ (dil.) }\underset{\mathrm{cold}}{⟶}\\ & 3{\mathrm{Cl}}_2+6\mathrm{NaOH}\text{ (conc.) }\underset{5\mathrm{NaCl}}{\stackrel{\text{ heat }}{⟶}}+\mathrm{NaOCl}+{\mathrm{H}}_2\mathrm{O}\\ & {\mathrm{NaClO}}_3+3{\mathrm{H}}_2\mathrm{O}\end{array}$$ Chlorine undergoes the simultaneous oxidationreduction. Chlorine is simultaneously reduced to chloride ion $\left({\mathrm{Cl}}^{-}\right)$and is oxidised to either ${\mathrm{ClO}}^{-}$ or ${\mathrm{ClO}}_3^{-}$ion. Halogens (e.g. Cl) have a strong tendency to accept electrons, so they act as strong oxidising agents.
