Cysteine Like other amino acids, cysteine has an amphoteric character.
Acid dissociation constant An amphoteric substance is one that can act as an acid or as a base, depending on pH. Water (above) is amphoteric. Another example of an amphoteric molecule is the bicarbonate ion that is the conjugate base of the carbonic acid molecule HCO in the equilibrium
Scandium The oxide ScO and the hydroxide Sc(OH) are amphoteric:
Amphoterism In chemistry, an amphoteric compound is a molecule or ion that can react both as an acid as well as a base. Many metals (such as copper, zinc, tin, lead, aluminium, and beryllium) form amphoteric oxides or hydroxides. Amphoterism depends on the oxidation states of the oxide. Al2O3 is a amphoteric oxide
Amphotericin B Amphotericin name originates from the chemical's amphoteric properties.
Amphoterism Metal oxides which react with both acids as well as bases to produce salts and water are known as amphoteric oxides. Amphoteric oxides include lead oxide and zinc oxide, among many others.
Hydroxide Aluminium hydroxide Al(OH) is amphoteric and dissolves in alkaline solution.
Uranium trioxide Uranium oxide is amphoteric and reacts as acid and as a base, depending on the conditions.
Disodium cocoamphodiacetate Disodium cocoamphodiacetate (DSCADA) is a synthetic amphoteric surfactant routinely used in personal care products.
Copper(II) hydroxide Copper(II) hydroxide is mildly amphoteric. It dissolves slightly in concentrated alkali, forming [Cu(OH)].
Indium(III) oxide Indium(III) oxide (InO) is a chemical compound, an amphoteric oxide of indium.
Acid dissociation constant Thus the zwitterion, , is amphoteric because it may either be protonated or deprotonated.
Hydroxide The amphoteric hydroxide Al(OH) has four major crystalline forms: gibbsite (most stable), bayerite, nordstrandite and doyleite.
Hordenine Since the hordenine molecule contains both a basic (amine) and acidic (phenol) functional group, it is amphoteric.
Compounds of zinc Zinc oxide, ZnO, is the most important manufactured compound of zinc, with a wide variety of uses. It crystallizes with the Wurtzite structure. It is amphoteric, dissolving in acids to give the aqueous Zn ion and in alkali to give the zincate (a.k.a. tetrahydroxozincate) ion, [Zn(OH)]. Zinc hydroxide, Zn(OH) is also amphoteric.
Oxide Oxides can be reacted by acids or bases. Those reacted only by acids are basic oxides; those reacted only by bases are acidic oxides. Oxides that react with both acids and bases are amphoteric. Metals tend to form basic oxides, non-metals tend to form acidic oxides, and amphoteric oxides are formed by elements near the boundary between metals and non-metals (metalloids).
Zinc oxide Zinc oxide is an amphoteric oxide. It is nearly insoluble in water, but it will dissolve in most acids, such as hydrochloric acid:
Properties of water Water is amphoteric, meaning it is both an acid and a base—it produces and ions by self ionization. This regulates the concentrations of and ions in water.
Amphoterism Some other elements which form amphoteric oxides are gallium, indium, scandium, titanium, zirconium, vanadium, chromium, iron, cobalt, copper, silver, gold, germanium, tin, antimony, bismuth, and tellurium
Lead dioxide Lead dioxide is an amphoteric compound with prevalent acidic properties. It dissolves in strong bases to form the hydroxyplumbate ion, Pb(OH):
