WebQuestion: Monochlorodecane, CHCI (MCD) is to be produced from decane, CH22 (DEC) and chlorine via the reaction below: Cl2 + Cl: CHCI + HCI A side reaction occurs in which dichlorodecane, CHCI (DCD) is produced: CroH2 + Co CaCl + HCI The by-product, DCD is not required for this project. HCI can be sold to a neighbouring plant. Component HCI … CrOH2+, Cr(OH)j , Cr(OH );, and Cr(OH~ (Rai, et al., 1987). At high concentrations, these ions impart a green color to the solution. Under slightly acidic to alkaline conditions, Cr(lll) can precipitate as an amorphous chromium hydroxide. Amorphous Cr(OH), can crystallize as Cr(OH)~. 3HZ0 or Cr20, (eskolaite) under different conditions ...

WebApr 3, 2015 · 2Cr (OH) 3 + 3H 2 SO 4 → Cr 2 (SO 4) 3 + 6H 2 O. Chromium (III) hydroxide react with sulfuric acid to produce chromium (III) sulfate and water. Sulfuric acid - diluted solution. WebThe redox reaction is shown below: Cr(OH) 3+(OH) −+IO 3−→CrO 42−+H 2O+I −. The oxidation number of I changes from +5 to −1. Thus, each iodine takes 6 electrons and is reduced. Hence, IO 3− is the oxidizing agent. The oxidation number of chromium changes from +3 to +6. Thus, Cr(OH) 3 is oxidized.
