Question

3) Given the 2nd series of experiments, consider these questions (24): For each of the reactions you ran, what is the balanced equation for each reaction? Cu(NO3)2 + Na Nal + FeCl3 Na + SnCl4 a. b. What is the balanced net ionic equation for each of them? Hint 1: Transition metals have multiple oxidation states and a redox reaction with them can also result in a change of oxidation state. Ex: Manganese in MnO4 (Permanganate) is reduced from an oxidation state of +7 to +4 when MnO2 product is generated from Permanganate reactions Hint 2: Recall that Iodine or 12 forms when Iodide is oxidized. Are the reactions you wrote in the previous part favorable? What evidence from your results supports your answer? To get full credit, you must address all 3 reactions c.

Explanation / Answer

Cu(NO3)2 + 2 NaI --> CuI2 + 2 NaNO3

2NaI + 2FeCl3 -> I2 + 2NaCl + 2FeCl2

4NaI + SnCl4 --> 4NaCl + SnI4
