Chaque atome d'hydrogène de l'ion ammonium peut être remplacé « substitué » par un groupe alkyle ou par un autre groupe organique constitué de chaînes carbonées ou d'autres substituants pour former un ion dit ammonium substitué, « ion ammonium » ou ions ammonium « primaire », « secondaire », « tertiaire » ou « quaternaire » (selon le nombre d'atomes d'hydrogène substitués). Ces ions sont les acides conjugués d'amines, sauf pour les ammoniums quaternaires qui ne peuv… Web3. why do you need ammonium ions and one sulfide for the formula for ammonium. Answer: Because the ammonium ion has a 1+ charge and the sulfide ion has a 2− charge, we need two ammonium ions to balance the charge on a single sulfide ion. 4.
