REACTION OF DICHROMATE WITH IODIDE<br />
(Variations Available)<br />
Adding Potassium Iodide To Sodium  Dichromate<br />
A redox reaction occurs between the 0.2M clear iodide solution, KI, & the 0.1M orange dichromate solution, Na2Cr2O7, producing a deep amber solution containing the Cr3+ (aq) and I2 (aq) ions.  -(Shortly after mixing solutions.)
