Is there a chemical test to see if the solution has potassium bromide without using an indicator and what is the chemical equation for it?© BrainMass Inc. brainmass.com June 23, 2018, 7:40 pm ad1c9bdddf
Silver(I) (Ag+) gives a pale yellow tinge in water and is insoluble in bromide. So, if you take a solution of your potassium bromide (KBr) and add a few drops of AgNO3 (silver nitrate) to solution, silver bromide (AgBr) will precipitate as pale yellow solid:
KBr + AgNO3 = KNO3 + AgBr(s) ...
The solution provides multiple methods to identify potassium bromide in a solution without using an indicator and provides a chemical equation for each method.
