What is a simple chemical test to distinguish between ammonia solution and ammonium bromide solution?
Please give any equations as well if you can.
Thankyou.

Add silver nitrate solution. Ammonium bromide will give an off-white precipitate of AgBr, while the solution of ammonia will do nothing.
AgNO3 + NH4Br ----> AgBr + NH4NO3

Ammonia gives a basic solution :
NH3 + H2O <---> NH4+ + OH-
NH4Br is a strong electrolyte
NH4Br >> NH4+ + Br-
It derives from a weak base ( NH3) and a strong acid HBr so the hydrolysis of this salt gives an acidic solution.
To distinguish between these two solution wecan use a pH-meter or an indicator
