It has a "rotten egg" odor characteristic of sulfur compounds, and produces hydrogen sulfide gas when reacted with mineral acids. Amorphous indium oxide is insoluble in water but soluble in acids, whereas crystalline indium oxide is insoluble in both water and acids. From Wikipedia, the free encyclopedia Indium (III) sulfide (Indium sesquisulfide, Indium sulfide (2:3), Indium (3+) sulfide) is the inorganic compound with the formula In 2 S 3. 0 … Give the noble gas configuration of indium(III) ion. 2 Answers. Physical properties Crystal structure. The In (III)-IIP prepared was repeatedly used and regenerated six times without a significant decrease in adsorption capacity, demonstrating that the sorbent is of high stability and reusability. The reaction of indium(III) and gallium(III) halides with Fe III (saen) 2 O in the majority of cases leads to products arising from halide exchange reactions However, in the reaction of InBr 3 with Fe III (saen) 2 O a product formulated as Fe III (saen)OlnBr 2 has been isolated. 1 decade ago. In the presence of sufficient chloride ions, Tl(III) forms the tetrachlorothallate(III), TlCl4 –, which forms a stable ion-pair association with the cationic part of methylene blue. Since the Roman numeral tells you the oxidation number of the metal, then the answer is (d). He had intended to investigate whether zinc sulfide ore (sphalerite) also contained thallium. Chloride compounds can conduct electricity when fused or dissolved in water. (hint: do not omit any subshells that may have lost electrons. Chloride materials can be decomposed by electrolysis to chlorine gas and the metal. In ion-exchange experiments, each crystalline sample (about 20 mg) of 1 – 4 was immersed in an aqueous solution of KCl, SrCl 2 , or BaCl 2 (10 mL, 1.0 M) in a 20-mL flask kept a constant temperature of 60 °C for 1 day.
