Is NH4Br an Acid or Base?
NH4Br is an acid. It is the salt of Hydrogen Bromide (HBr) and Ammonia (NH3). Here, it can be noted that HBr is a strong acid while NH3 is a weak base. The salts of strong acid and weak base are acidic in nature, therefore, NH4Br is acidic. It has a pKa value of ~5 in the water and a pH value of less than 7.

21.8: Quaternary Ammonium Salts: Hofmann Elimination
Elimination reactions of 4º-ammonium salts are termed Hofmann eliminations. Since the counter anion in most 4º-ammonium salts is halide, this is often replaced by the more basic hydroxide ion through reaction with silver hydroxide (or silver oxide). The resulting hydroxide salt must then be heated (100 - 200 ºC) to effect the E2-like ...
