WebThe number of millimoles of K2Cr2O7 reacting with solid KI during the analysis of the constituents of Ist beaker is: (A) 0.257 m moles (B) 0.129 m moles (C) 4.284 × 10–2 m … WebThus, in Na2Cr2O7, 2Na → +2, and 7O → -14. These add up to -12, so the 2Cr must be +12, and one Cr must be +6. In HCrO3-, H → +1 and 3O → -6. These add up to -5. Since the overall charge is 1-, the Cr is +4. So oxidation number of Cr changes from +6 to + 4. We are not saying that Cr6+ ions are converted to Cr4+ ions. fresh start gonoodle videos https://stork-net.com
