Suppose you have the following reagents available under standard conditions. (i.e., P = 1 atm for all gases; t = 25 oC; C = 1 mol L-1 for all aqueous species, including H+.) Co(s), Ag+(aq), Cl-(aq), Cr(s), BrO3-(aq), I2(s), F-(aq) (a) Which is the strongest oxidizing agent? (b) Which is the strongest reducing agent? (c) Which of the available reagent(s), if any, will oxidize Fe(s) while leaving Cu(s) unreacted? If none of the available reagents can be used for this purpose, then identify another reagent from the table that could be used. For each reagent you've identified, write down a balanced chemical equation for the reaction that occurs.
