- In chemistry, an
amphoteric compound (from Gr**** amphoteros 'both') is a
molecule or ion that can
react both as an acid and as a base. What

amphoteric, such as ****nic, antimony, vanadium, chromium, molybdenum, tungsten,...
- polymorphs: bayerite, doyleite, and nordstrandite.
Aluminium hydroxide is
amphoteric, i.e., it has both
basic and
acidic properties.
Closely related are aluminium...
-
other alkali metals are also
strong bases.
Beryllium hydroxide Be(OH)2 is
amphoteric. The
hydroxide itself is
insoluble in water, with a
solubility product...
- an acid is only such in
relation to a base, and vice versa.
Water is
amphoteric as it can act as an acid or as a base. In the

compounds are (covalent)
coordination complexes. The
oxide (PtO2) is
amphoteric, with
acidic properties predominating; it can be
fused with
alkali hydroxides...
- head with two
oppositely charged groups, it is
termed zwitterionic, or
amphoteric.

Disodium cocoamphodiacetate (DSCADA) is a
synthetic amphoteric surfactant routinely used in
personal care products. A 2008

hydroxide does not
attack iron at room temperature,
since iron does not have
amphoteric properties (i.e., it only
dissolves in acid, not base). Nevertheless,...
