The precipitation of indium hydroxide was a step in the separation of indium from zincblende ore by Reich and Richter, the discoverers of indium. [6] Indium(III) hydroxide is amphoteric, like gallium(III) hydroxide (Ga(OH) 3) and aluminium hydroxide (Al(OH) 3), but is much less acidic than gallium hydroxide (Ga(OH) 3), [5] having a lower ...
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Indium trihydride is an inorganic compound with the chemical formula (InH 3). It has been observed in matrix isolation and laser ablation experiments. [2] [3] Gas phase stability has been predicted. [4] The infrared spectrum was obtained in the gas phase by laser ablation of indium in presence of hydrogen gas [5] InH 3 is of no practical ...
A flame test involves introducing a sample of the element or compound to a hot, non-luminous flame and observing the color of the flame that results. [4] The compound can be made into a paste with concentrated hydrochloric acid, as metal halides , being volatile, give better results. [ 5 ]
Mixed flowing gas (MFG) is a type of laboratory environmental testing for products, particularly electronics, to evaluate resistance to corrosion due to gases in the atmosphere. Mixed Flowing Gas (MFG) test is a laboratory test in which the temperature (°C), relative humidity (%RH), concentration of gaseous pollutants (in parts per billion ...
Cerium(III) fluoride – CeF 3; Cerium(III) hydroxide – Ce(OH) 3; Cerium(III) iodide – CeI 3; Cerium(III) nitrate – Ce(NO 3) 3; Cerium(III) oxide – Ce 2 O 3; Cerium(III) sulfate – Ce 2 (SO 4) 3; Cerium(III) sulfide – Ce 2 S 3; Cerium(IV) hydroxide – Ce(OH) 4; Cerium(IV) nitrate – Ce(NO 3) 4; Cerium(IV) oxide – CeO 2; Cerium(IV ...
Pourbaix diagram of iron. [1] The Y axis corresponds to voltage potential. In electrochemistry, and more generally in solution chemistry, a Pourbaix diagram, also known as a potential/pH diagram, E H –pH diagram or a pE/pH diagram, is a plot of possible thermodynamically stable phases (i.e., at chemical equilibrium) of an aqueous electrochemical system.
Indium reacts with water to reproduce soluble indium(III) hydroxide, which is also amphoteric; with alkalis to produce indates(III); and with acids to produce indium(III) salts: In(OH) 3 + 3 HCl → InCl 3 + 3 H 2 O. The analogous sesqui-chalcogenides with sulfur, selenium, and tellurium are also known. [39] Indium forms the expected trihalides.
