Which of the following is used to iodise common salt? (1) Potassium iodide (2) Iodine (3) Potassium iodate (4) Sodium iodide
by

1 Answer

Answer :

(3) Potassium iodate Explanation: Iodized salt (also spelled iodised salt) is table salt mixed with a minute amount of various salts of the element iodine. Table salt with iodide salt slowly loses its iodine content through the process of oxidation and iodine evaporation. Edible salt can be iodised by spraying it with a potassium iodate solution. 60 ml of potassium iodate.
