Question

Is table salt a mixture?

Answer 1

Table salt is `97% to 99%` sodium chloride, with trace elements of other salts, plus added anti-clumping agents and iodine added during processing. In that respect it is a crystalline mixture.

Explanation:

Sodium in moderation is necessary to all animal life where it keeps our nerves and muscles working. Additives in table salt include iodine to keep thyroids healthy.

Anti-clumping agents keep salt from becoming a large solid ball in the presence of moisture. In some countries salts of iron are also added to table salt to contend with iron deficiency anemia.
