Question

if sodium and chlorine are poisonous in nature then why we use them as common salt???

Answer 1

Hey...
Sodium chloride is always formed by the neutralization reaction of sodium hydroxide and hydrochloric acid. Water is formed in this reaction. So it is a neutral reaction. Sodium chloride formed is neutral. Hence, we use it as common salt in food items.
