Difference Between Potassium Iodide and Potassium Iodate

Thekey differencebetween potassium iodide and potassium iodate is thatpotassium iodide is less effective in blocking radiation compared to potassium iodate.

Both potassium iodide and potassium iodate are salts ofpotassium, and they occur as a white, crystalline powder. Both these compounds are important as dietary supplements. One of the major applications of these compounds is in the process of blocking radiation. Here, potassium iodate is more effective than potassium iodide because potassium iodide has a poor shelf life at hot and humid climates.

What is Potassium Iodide?

Potassium iodide is an inorganic compound that has the chemical formula KI. In a commercial scale, it is produced by mixingpotassium hydroxidewithiodine. Besides, it is useful as a medication and as a dietary supplement as well. Concerning its properties, the molar mass of KI is 166 g/mol. The melting point is 681 °C, and the boiling point is 1,330 °C.

As a medication, it is important to treat hyperthyroidism. Moreover, it is very important in radiation emergencies. However, scientists have found now that this compound is less effective in blocking radiation because it has a poor shelf life in hot and humid climates.

The side effects that occur due to the consumption of potassium iodide include vomiting, diarrhoea, abdominal pain, rashes, swelling of salivary glands, etc. Other than that, some people are allergic to this medication while some others show symptoms like headaches, goitre and depression.

What is Potassium Iodate?

Potassium iodate is an inorganic compound that has the chemical formula KIO3. It is useful for iodination of table salt. Hence, it is a source of dietary iodine. For instance, it is a component in baby formula milk. Concerning its properties, the molar mass of it is 214 g/mol. Moreover, its melting point is 560 °C and heating further will decompose the compound.

Besides, it is also commonly known for its ability to block radiation in an emergency. In fact, it is more effective than potassium iodide as this compound has a better shelf life in hot and humid climates.

What is the Difference Between Potassium Iodide and Potassium Iodate?

Potassium iodide is an inorganic compound that has the chemical formula KI. Potassium iodate is an inorganic compound that has the chemical formula KIO3. The key difference between potassium iodide and potassium iodate is that potassium iodide is less effective in blocking radiation compared to potassium iodate.

Further, the molar mass of potassium iodide is 166 g/mol, and for potassium iodate, it is 214 g/mol. When considering the melting and boiling points, the melting point of potassium iodide is 681 °C and the boiling point is 1,330 °C while the melting point of potassium iodate is 560 °C and heating further will decompose the compound.

Below infographic provides more information regarding the difference between potassium iodide and potassium iodate.

Summary – Potassium Iodide vs Potassium Iodate

Both potassium iodide and potassium iodate are important in blocking radiation. In summary, the key difference between potassium iodide and potassium iodate is that potassium iodide is less effective in blocking radiation compared to potassium iodate.
