========================================

Distinguish between normal salt and iodized salt.
___________________________________

1)The iodised salt has less taste than normal salt.

2) Dissolve 4 tablespoons of salt in one cup distilled water.We don't know the salt.Then add one tablespoon vinegar,one tablespoon Hydrogen peroxide and half tablespoon starch.If the solution shows purple-blue like colour then it is iodised salt.If the color didn't change then it is normal salt.

1) iodised salt contain iodine which helps to prevent iodine deficiency in human body.Normal salt doesn't contain iodine.

2) Iodised salt has more health benefits than normal salt.
