Question

What happens to the the boiling point of water, when table salt is added to it?

• A. Boiling point remains same
• B. Boiling point increases
• C. Boiling point decreases
• D. Can't be said

Answer 1

The correct option is B Boiling point increases

Table salt also known as sodium chloride (NaCl) is a soluble salt.
Presence of soluble salts increases the boiling point of water because, salt is a non -volatile solute which is responsible for boiling point elevation because sodium chloride dissociates into sodium and chlorine ions . These charged particles alter the intermolecular forces between water molecules and also induces ion-ion dipole interaction which is more stronger than hydrogen bond and hence leads to the elevation of boiling point.
