Amorphous indium oxide is insoluble in water but soluble in acids, whereas crystalline indium oxide is insoluble in both water and acids. The crystalline form exists in two phases, the cubic (bixbyite type) [1] and rhombohedral (corundum type). Both phases have a band gap of about 3 eV. [3] [4] The parameters of the cubic phase are listed in ...
In organic chemistry and biochemistry, important examples include amino acids and derivatives of citric acid. Although an amphiprotic species must be amphoteric, the converse is not true. For example, a metal oxide such as zinc oxide, ZnO, contains no hydrogen and so cannot donate a proton. Nevertheless, it can act as an acid by reacting with ...
Although most compounds are referred to by their IUPAC systematic names ... Indium(I) oxide – In 2 O; Indium(III) oxide – In 2 O 3; Iodine pentoxide – I 2 O 5;
Boron oxide (B 2 O 3) is slightly acidic, aluminium and gallium oxide (Al 2 O 3 and Ga 2 O 3 respectively) are amphoteric, indium(III) oxide (In 2 O 3) is nearly amphoteric, and thallium(III) oxide (Tl 2 O 3) is a Lewis base because it dissolves in acids to form salts. Each of these compounds are stable, but thallium oxide decomposes at ...
Indium(I) compounds are not common. The chloride, bromide, and iodide are deeply colored, unlike the parent trihalides from which they are prepared. The fluoride is known only as an unstable gas. [42] Indium(I) oxide black powder is produced when indium(III) oxide decomposes upon heating to 700 °C. [38]
Indium compounds are chemical compounds that contain the chemical element indium ... Indium tin oxide; Indium trihydride; Indium(I) iodide; Indium(II) chloride;
A chemical bond between valence electrons, or an atom or unbranched chain of atoms connecting two different parts of the same molecule; i.e. an intramolecular bond linking different moieties or functional groups. [2] bridgehead Either of the two tertiary atoms which by bonding to each other form an intramolecular bridge. [2] Brønsted–Lowry acid
Numerous investigations have found an explanation for this effect. The oxygens of the carbonyl and the hydroxyl group chelate the indium of the organoindium intermediate as illustrated below on the left by the two green bonds. The incipient C-C bond, illustrated in red, creates a six-member ring in a chair conformation.
