Answer:

Explanation:

If we consider Iodized table salt  (the most common type) then no, it's not a pure substance because you can remove the iodine without changing the chemical nature of the substance. Iodized table salt is a mixture, not a pure substance.

While, NaCl with no iodine is a pure substance.

Coz,

Table salt is composed of sodium and chlorine, NaCl. It's a compound of two distinct elements that cannot be broken down further without changing the properties of the substance. If you were to take one molecule of NaCl and divide it further, you would no longer have table salt; you would have a sodium atom and a chlorine atom.

“Sugar” usually refers to refined cane or beet sugar, which is sucrose. There are many kinds of sugars, but this is the most common commercial product.

It’s a pure substance because it consists of one kind of molecule. Refining incluces several processes that remove other things (such as the cellulose) from the beets or cane. Refined sugar has well defined physical and chemical properties that make it very useful in product: well defined solubility, melting point, chemical changes at various temperatures, sweetness, etc.
