The oxidation state of chromium in cr co 6 is
WebbChromium is a chemical element which has the symbol Cr and atomic number 24. It is found naturally occuring in rocks, animals, plants, and soil, and is usually mined as chromite ore. Chromium is most toxic in its +6 oxidation state ( chromium(VI) ) due to its greater ability to enter cells and higher redox potential. Webb28 mars 2024 · Let the oxidation state be 'x' of Chromium in K2Cr2O4. Four oxygen atoms give us - 2 × 4 = -8 charge. The metal ion is in a unipositive state, so two K + ions will provide a +2 charge. The molecule as a whole has no charge, it is neutral. Hence, the equation for charges is: x + 2 + ( -8 ) = 0, or, x - 6 = 0, or x = 6
