2. Solid zinc reacts with a chromium nitrate solution to produce solid chromium and an aqueous zinc nitrate. Chromium has multiple oxidation states, including Cr+2, Cr+4, Cr+6. The balanced reaction for the Cr+2 ion with Zn is below Zn + Cr(NO3)2 → Zn(NO3)2 + Cr a. Write a balanced reaction for the reaction between chromium(IV) nitrate and zinc, and for the reaction between chromium(VI) nitrate and zinc. b. If 2.00 g Zn is reacted with an excess of a chromium nitrate solution of unknown composition (Cr+2, Cr+4, or Cr+6) to produce 0.53 g of solid chromium. What was the initial oxidation state of the chromium nitrate solution (Cr+2, Cr+4, or Cr+6)?
