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+ + H2O
In bases: ZnO + H2O + 2OH- → [Zn(OH)4]2-
This effect can be used to separate different cations, such as zinc from manganese.

Is ciprofloxacin acidic basic amphoteric or neutral?
amphoteric
What is a common amphoteric substance?
Water is an amphoteric substance.
Is Glycine amphoteric?
Yes, Glycine is amphoteric. It can act as an acid or as a base (or alkaline).
Beryllium oxide is amphoteric prove with examples?
Yes, beryllium oxide is amphoteric because can be dissolved by acids and bases..
Is salt amphoteric?
Sodium chloride is not amphoteric.
What is an amphoacetate?
An amphoacetate is an amphoteric acetate, especially a salt of an acetic acid which has a basic substituent.
Is ammonium ethanoate an acid or a base?
Base and acid. Ammonium ethanoate is am amphoteric salt.
What is an amphopropionate?
An amphopropionate is an amphoteric propionate, especially a salt of a propionic acid which has a basic substituent.
Is Al2O3 an acid base salt or oxide?
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.
Is a bicarbonate ion an amphoteric substance?
amphoteric
Is ciprofloxacin acidic basic amphoteric or neutral?
amphoteric
What is a common amphoteric substance?
Water is an amphoteric substance.
Is ammonia an amphoteric substance?
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.
Does sodium calcium are amphoteric oxides?
The oxides of sodium and calcium are not amphoteric: They are strongly basic. The most common amphoteric oxides are silica and alumina.
Is copper oxide a basic or amphoteric oxide?
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)
Is sulphate ion 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
