Clorine reaction w cold dilute alkalis
Cl + NaOH —-> NaCl + NaOCl + H2O (Milton solution)
Reaction of Chlorine with hot alkalis
Cl + NaOH —> NaCl + NaOCl3 + H2O
How does Br and I react with either cold/hot cocentrated or dilute alkalis?
Br2 + NaOH —-> NaBr + NaBrO3 + H2O
I2 + NaOH —–> NaI + NaIO3 + H2O
