Question

A galvanic cell at a temperature of 25.0 °C is powered by the following redox reaction: 2IO?? (aq) + 12H? (aq) + 5Co (s) ? I? (s) + 6H?O (l) + 5Co²? (aq) Suppose the cell is prepared with 1.98 M IO?? and 1.29 M H? in one half-cell and 3.04 M Co²? in the other. Calculate the cell voltage under these conditions. Round your answer to 3 significant digits.

Step 1

The given reaction is not balanced, so let's balance it: 2IO₃⁻(aq) + 12H⁺(aq) + 10Co²⁺(aq) → 6H₂O(l) + 5Co(IO₃)₂(s) Now, we need to find the standard cell potential (E°) for this reaction. We can do this by looking up the standard reduction potentials for the Show more…
