Sodium bromides bromide ion can be substituted by fluorine, and chlorine. 

Sodium bromide can be oxidized by oxygen and release free bromine; this process is taken advantage of by industry for producing bromine. 
Sodium bromide can have reaction with dilute sulfuric acid to produce hydrogen bromide. However, hydrobromic acid is a strong acid which can’t be produced through the reaction with dilute sulfuric acid and can only made through high-boiling point acid to make low-boiling point acid. 
However, we should avoid to use concentrated sulfuric acid which has strong oxidation effect and thus converting bromine (-1) into bromine element and release reddish-brown gas. 

This method can be used to identify sodium iodide (Heating sodium iodide and concentrated sulfuric acid together will release red-purple gases), Thereby, we can only take the concentrated phosphoric acid together with sodium bromine for heating to produce hydrogen bromine.
