Ammonium Salts are ionic compounds with the formula (R)4N+A-, where R is hydrogen, alkyl or aryl groups and A is an anion.
When R is alkyl or aryl then they are referred to as quaternary ammonium salts.
The quaternary ammonium cations are permanently charged, independent of the pH of their solution.
The ammonium cation is a positively charged polyatomic ion with the chemical formula NH⁺ ₄.
It is formed by the protonation of ammonia.
