Ammonium - Wikipedia
The ammonium ion is generated when ammonia, a weak base, reacts with Brønsted acids (proton donors): H + NH3 → [NH4] The ammonium ion is mildly acidic, reacting with Brønsted bases to return to the uncharged ammonia molecule: [NH4] + B → HB + NH3 Thus, the treatment of concentrated solutions of … 展开
Ammonium is a modified form of ammonia that has an extra hydrogen atom. It is a positively charged (cationic) molecular ion with the chemical formula NH+4 or [NH4] . It is formed by the addition of a proton (a hydrogen nucleus) to … 展开
