At red hot, antimony reacts with water to form the trioxide antimony(III) oxide, Sb 2 O 3. Unlike oxides of phosphorus and arsenic, these oxides are amphoteric, do not form well-defined oxoacids, and react with acids to form antimony salts. The acidic behavior can be described by the reactivity of the anions. An amphoteric compound is one that can react with both acids and bases.. Amphoteric behavior applies to acids and bases defined in the Bronsted-Lowry sense and in the wider Lewis sense.. The halogens attack it vigorously.

Amphoteric definition is - partly one and partly the other; specifically : capable of reacting chemically either as an acid or as a base. It is an amphoteric oxide, which can dissolve both in ukraine and acidic solutions. Some non-metal oxides, such as nitrous oxide (N2O) and carbon monoxide (CO), do not display any acid/base characteristics. Like most polymeric oxides, Sb2O3 dissolves in aqueous solutions only with hydrolysis. *Response times vary by subject and question complexity. For example, NO, The nature of oxides of group 15 elements is as follows, N. Take your favorite fandoms with you and never miss a beat. Amphiprotic molecules, such as amino acids and proteins, are amphoteric. Ampholytes are amphoteric molecules that contain both acidic and basic groups and will exist mostly as zwitterions in a certain range of pH. Antimony trioxide also dissolves in concentrated acids to give the corresponding salts, which hydrolyzes upon dilution with water. Metal oxides or hydroxides are amphoteric.
