I would guess that this is so because of potassium's mass, being much more than, sodium's molar mass per ion. So can sodium iodide be used instead of potassium iodide? Perhaps, but maybe not to the same level effectiveness. Potassium molecules have been known to dissolve better than sodium molecules. One example is Potassium Chloride and Sodium Chloride thanks

What is the function of potassium iodide in iodometric titration?
Potassium iodide is used in iodometric titration as a source of iodide ions. It reacts with iodine to form triiodide ions, which are then titrated with a standard solution of thiosulfate to determine the concentration of the oxidizing agent.
Why the amount of potassium iodide to potassium iodateV does not affect the iodine liberated in iodometric titration?
The amount of potassium iodide does not affect the iodine liberated because potassium iodide is used as a reducing agent in the reaction, converting iodate to iodine. The stoichiometry of the reaction ensures that the amount of iodine liberated is solely determined by the initial amount of iodate present, not the amount of potassium iodide added.
What is oxygen error in association with iodometric titrations what can you do to overcome?
Oxygen error in iodometric titrations occurs when oxygen in the atmosphere reacts with iodide ions, interfering with the titration results. To overcome this, the sample can be titrated in an inert atmosphere or by adding a reducing agent to remove the dissolved oxygen. Another approach is to boil the sample to remove the dissolved oxygen before titration.
Why potassium iodide added in excess?
Potassium iodide is added in excess in order to ensure that all available iodine is converted to iodide ions, which are then neutralized by thiosulfate ions in the back-titration method for determining the concentration of oxidizing agents, such as in the iodometric method. This ensures accurate and precise results by guaranteeing the complete reaction of all the iodine formed in the titration.
What compound are in potassium iodide?
Potassium iodide (KI) contain I and K and is an ionic compound.

Does the amount of potassium iodide added to the potassium iodate solution affect the amounts of iodine liberated in iodometric titration?
Yes, the amount of potassium iodide added to the potassium iodate solution in iodometric titration affects the amount of iodine liberated. Potassium iodide serves as a reducing agent, reacting with the iodate ion to form iodine. The quantity of potassium iodide added determines the rate and completeness of this reaction, impacting the amount of liberated iodine available for titration.

What is the chemical name of potassium iodide?
The same, Potassium iodide
What is a potassium iodide?
Potassium iodide is KI (K+ and I-)
What is the chemical name for KI?
Potassium Iodide
Is iodide and potassium iodide the same?
No, iodide refers to the ion I-, whereas potassium iodide is a chemical compound made up of both potassium (K+) and iodide ions (I-). When iodide is combined with potassium as in potassium iodide, the resulting compound has different properties and uses compared to just iodide alone.
In potassium iodide what is the cation?
Potassium, K+, is a cation
