Question

Why table salt should be in tight containers

Answer 1

 Table salt is the refined white crystal typically found in a salt shaker. It usually comes in a cardboard can and is the cheapest salt on the shelf at the grocery store. You can buy it with or without iodine added (more on that later). It generally contains an anti-clumping agent.so table salt should be in tight containers

Answer 2

Answer:

As we know that iodised salt contains iodine which one exposure to air may sublime. So it should be stored in airtight containers to protect and preserve the iodine.
