Which salt produces the least salt hydrolysis in an aqueous solution?

Elodia [21]

Answer:

Potassium Iodide

Step-by-step explanation:

KI (potassium iodide) is a salt of stable (not radioactive) iodine that can help block radioactive iodine from being absorbed by the thyroid gland, thus protecting this gland from radiation injury. The thyroid gland is the part of the body that is most sensitive to radioactive iodine.
