Bromate Ions are titrated against hydroxylammonium ions in order to find the identity of an unknown compound containing nitrogen.

Bromate Ions are titrated against hydroxylammonium ions in order to find the identity of an unknown compound containing nitrogen. The balanced equation prior to identification was BrO3 – + NH3OH+ -> Br – + ? After identification of the compound, the balanced equation was found to be BrO3 – + NH3OH+ + H2O -> Br – + NO3- + 2H3O + . The titration involved the use of excess bromate ions to identify the unknown compound. Could this same experiment be formed with chromate or iodate ions in excess in opposition to bromate ions? If so, why?
