Examples of amphoteric substances include
water, amino acids, proteins, and many metal oxides and hydroxides
. Oxides and hydroxides of aluminum, antimony, arsenic, antimony, bismuth, beryllium, chromium, cobalt, copper, gallium, germanium, gold, iron, lead, silver, tellurium, tin, and zinc are amphoteric.

are common examples of amphiprotic species. Since they can donate a proton, all amphiprotic substances contain a hydrogen atom.
What are amphoteric substances Class 11?
Hint: The term amphoteric means
the given substance can react with both acid and as a base
. That means it can act as a proton donor as well as a proton acceptor. … It also acts as an acid and a base both. The most common amphoteric substance in the world is water. A hydrogen atom has an electron and a proton.
What are amphoteric give two examples?
- ZnO(s) + 2HCl(aq) → ZnCl2(aq) + H2O(l)
- ZnO(s) + 2NaOH(a) → Na2ZnO2(aq) + H2O(l)
- Al2O3(s) + 6HCl(aq) → 2AlCl3(aq) + 3H2O(l)
- Al2O3(s) + 2NaOH(aq) → 2NaAlO2(aq) + H2O(l)
What is a Amphiprotic substance?
In chemistry and physical sciences, a substance is described as amphiprotic
if it can both donate or accept a proton
, thus acting either like an acid or a base (according to Brønsted-Lowry theory of acids and bases: acids are proton donors and bases are proton acceptors.
How do you identify an Amphiprotic substance?
An amphiprotic substance can
accept or donate at least one proton, usually H+
. So in order for a substance to be amphiprotic, it must be able to accept an H+ ion or give away an H+ ion. An example would be (HCO3)^-. It can accept a proton to become (H2CO3), or it can donate away its proton to become (CO3)^2-.
What is the most common Amphiprotic substance?
Molecules or ions which can either donate or accept a proton, depending on their circumstances, are called amphiprotic species. The most important amphiprotic species is
water itself
. When an acid donates a proton to water, the water molecule is a proton acceptor, and hence a base.
What does ampholytic mean?
adjective Chemistry.
capable of ionizing into both anions and cations
; amphoteric.
Is H3O+ Same as H+?
The H3O+ ion is
considered to be the same as the H+ ion
as it is the H+ ion joined to a water molecule. The proton cannot exist in aqueous solution, due to its positive charge it is attracted to the electrons on water molecules and the symbol H3O+ is used to represent this transfer.
Is H2PO2 amphoteric?
A specie that can accept H+ , as well as
loose H+ is considered amphoteric in nature
. In option B, H2PO2- can’t loose H+ ion as it’s a conjugate base of hypophosphorus acid H3PO2 which is mono basic.
Is al2o3 amphoteric?
Aluminium oxide is
an amphoteric oxide
because it reacts with acids as well as bases and gives salts and water. Aluminium has electronegativity 1.5.
What is amphoteric in nature?
An amphoteric compound is
a molecule or ion that can react both as an acid and as a base
. Since water has the potential to act both as an acid and as a base, water is amphoteric .

Is na2o amphoteric?
On moving down in different groups the variation in oxides is different . Hence , from the given options
ZnO is amphoteric oxide

Is ZnO amphoteric?
Zinc oxide is amphoteric
because it reacts with both acids and bases to form salts.
Is CO2 amphoteric?
The correct option is: a
SnO2
Explanation:SnO2 reacts with acid as well as base. So SnO2 is an amphoteric. CaO is basic in nature while SiO2 and CO2 are acidic in nature.
