What would likely occur if #"potassium iodide"# were added to #"ferric nitrate"#?
This is a type of metathesis reaction, i.e. a partner exchange reaction. Neither of the products are particularly insoluble, and they would remain in solution as the aquated ions, i.e.
Additional redox reactions are conceivable, i.e. reduction of ferric to ferrous ion, or oxidation of iodide ion to tri-iodide, i.e.
Oxidation of the iodide anion might indeed drive the ferric ion reduction. The
