amphoteric
sulphate ion is not amphoteric because according to Bronsted-Lowry concept an amphoteric specie is that which can donate as well as accept aproton but sulphate ion is not capable of donating proton so it is not amphoteric
No, the ammonium ion is not considered an amphoteric species because it can only act as an acid by donating a proton. Amphoteric species can act as both an acid and a base by accepting or donating a proton.
It is called the Sulphide ion
Sulfide typically carries a charge of -2. This is because sulfur, the element that makes up sulfide, usually contributes two electrons to form a stable ionic or covalent bond with other elements.
A substance that can act as both an acid and a base is called amphoteric. This means it can either donate or accept a proton, depending on the reaction conditions. Water is a common example of an amphoteric substance.

Sulphur
Amphoteric metals are elements that can act as both acids and bases in a chemical reaction. This means they have the ability to donate or accept a proton depending on the reaction conditions. Some examples of amphoteric metals include aluminum, zinc, and lead.
The formula for the ionic compound composed of barium and sulfide is BaS. Barium is a group 2 element with a 2+ charge, and sulfide is a group 16 element with a 2- charge. This results in a one-to-one ratio of ions in the formula.
-2 is the most common charge (sulphide ion).
it is S2- ,while sulphite ion is SO32-
