does anyone know what the resultant of these two equations are used in the real world?

Cl2 + 2NaBr → 2NaCl + Br2


Br2 + 2KI → 2KBr + I2

[ajkoer]

These reactions are completely accurate when heating together the dry salts. Perhaps better described as:

Cl2 (g) + 2 NaBr (s) → 2 NaCl (s) + Br2 (g)


Br2 (l) + 2 KI (s) → 2 KBr (s) + I2 (g)

However, if an aqueous solution then things get more complex due to disproportionation reactions, as for example:

 Br2 + H2O <---> HOBr + HBr

 3 HOBr --> HBrO3 + 2 HBr

which then react with the KI.
