Cobalt sulfide is the name for chemical compounds with a formula Co x S y. Well-characterized species include minerals with the formulas CoS, CoS 2 , Co 3 S 4 , and Co 9 S 8 . In general, the sulfides of cobalt are black, semiconducting , insoluble in water, and nonstoichiometric .

2021年2月3日 · To write the formula for Cobalt (III) sulfide we’ll use the Periodic Table and follow some simple rules. --Keys for Writing Formulas for Compounds with Transition Metals-- 1. Write the symbol...

2024年10月16日 · In cobalt (III) sulfide, cobalt is in the +3 oxidation state (Co³⁺). Sulfide (S) has a charge of -2 (S²⁻). To form a neutral compound, the total positive charge must equal the total negative charge. Since cobalt is +3, we need to determine how many cobalt ions are required to balance the charge of sulfide ions. Each sulfide ion has a charge of -2.

2009年3月21日 · Cobalt sulfide precipitates when aqueous solutions of cobalt (II) ions are treated with hydrogen sulfide. It is used as a catalyst for the industrial process called hydrodesulfurization, which is implemented on a large scale in refineries. Cobalt is a …
