Chromium(III) oxide reacts with hydrogen s... | Clutch Prep

Chromium (III) sulfate usually refers to the inorganic compounds with the formula Cr 2 (SO 4) 3. x (H 2 O), where x can range from 0 to 18. Additionally, ill-defined but commercially important "basic chromium sulfates" are known. These salts are usually either violet or green solids that are soluble in water.Explanation: Chromium III (Cr) has a charge of 3+ Sulphur (S) has a charge of 2- When you cross the charges, Chromium ends up having 2 atoms and Sulphur ends up needing 3 atoms, as seen in the formula aboveChromium(III) sulfide appears as a brownish black powder that melts at 1350 C. It is essentially insoluble in water. When heated sufficiently, it will oxidize in the presence of air or oxygen, though it is otherwise fairly stable. Health effects. Chromium (VI) is a confirmed carcinogen in humans. Because chromium(III) sulfide is fairlyChromium(III) oxide reacts with hydrogen sulfide (H2S) gas to form chromium(III) sulfide and water: \mathrm{Cr}_{2} \mathrm{O}_{3}(s)+3 \mathrm{H}_{2} \mathrm{…Chromium(III) Sulfide is the inorganic compound with the formula Cr2S3. It is a brown-black solid. Chromium sulfides are usually nonstoichiometric compounds, with formulas ranging from CrS to Cr0.67S (corresponding to Cr2S3).
