1. Mixture of potassium iodide and common salt
2. Mixture of molecular iodine and common salt
3. Compound formed by combination of molecular iodine and common salt
4. Only potassium iodide

Answer 1

Correct Answer - Option 1 : Mixture of potassium iodide and common salt

The correct answer is a mixture of potassium iodide and common salt.

• Iodised salt is a mixture of potassium iodide and common salt.

 

• Iodised salt is table salt mixed with a minute amount of potassium iodide of the element iodine.
• The ingestion of iodine prevents iodine deficiency.
• Deficiency also causes thyroid gland problems, including "endemic goitre".
• Iodine is a micronutrient and dietary mineral that is naturally present in the food supply in some regions, especially near sea coasts.
• Where natural levels of iodine in the soil are low and the iodine is not taken up by vegetables, iodine added to salt provides the small but essential amount of iodine needed by humans.
