Sodium chloride is not amphoteric.
Base and acid. Ammonium ethanoate is am amphoteric salt.
An amphoacetate is an amphoteric acetate, especially a salt of an acetic acid which has a basic substituent.
An amphopropionate is an amphoteric propionate, especially a salt of a propionic acid which has a basic substituent.
It is an AMPHOTERIC oxide. That is , in an environment of low(acid) pH it behaves as a BASE. In an environment of high(alkaline) pH it behaves as an ACID.

Water is an amphoteric substance.
Inchemistry, an amphoteric substance is one that can react as either an acid or base.Many metals (such as zinc, tin, lead, aluminium, and beryllium) and most metalloids have amphoteric oxides or hydroxides.Zinc oxide (ZnO) reacts differently depending on the pH of the solution:In acids: ZnO + 2H+ → Zn2+ + H2OIn bases: ZnO + H2O + 2OH- → [Zn(OH)4]2-This effect can be used to separate different cations, such as zinc from manganese.
No, in order for a substance to be considered amphoteric it must be able to act as an acid and a base. Sodium sulfite will only act as a base, and thus it is not amphoteric.
The oxides of sodium and calcium are not amphoteric: They are strongly basic. The most common amphoteric oxides are silica and alumina.
amphoteric, it reacts with an acid or a base to form a salt and water (a neutralisation reaction) ZnO(s) + 2HCL (aq) = ZnCl2(aq) + H2O(l) ZnO (s) + 2OH- (aq) = ZnO22-(s) + H2O(l)
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
