Not usually. Potassium iodide is usually present in a large excess. It is usually the potassium iodate that is the limiting ingredient.
Yes, in small amounts. Potassium iodide is often added to table salt as a preventative against the disease goiter.

Iodometric titration means the titration of triiodide. Preparation of triiodide can be prepared by adding solid iodine to excess potassium iodide, however since iodine sublimes it is more difficult to weigh than potassium iodate. The triiodide would then need to be standardized with primary standard grade arsenious oxide. A better way is to weigh potassium iodate and add to a small excess of potassium iodide. The two ions (iodide and iodate) will also form the needed triiodide in an acidic environment. If the reagent is made fresh this way it can be used to standardize thiosulfate. Iodide iodate of known normality can also be used to titrate unknown concentrations of sulfite. For example, steam boiler treatment applications.

- potassium iodide is added to table salt as a source of iodine- potassium iodide is a food supplement during a nuclear accident in a nuclear reactor- for the preparation of AgI
This element is iodine, added as potassium iodide or potassium iodate.
Ag(NO3)(aq) + KI(aq) ---> K(NO3)(aq) + AgI(s)
Iodine is added to salt as potassium (sodium) iodide or potassium (sodium) iodate. An iodine deficiency is a source of thyroide diseases or can lead to idiocy.
