Identify if one mole of CaCl2 or one mole of NaCl will raise the boiling point of water higher. Explain.

Answer 1

Raising the b.p. Is a colligative property and as such, depends on the number of particles present. The more particles, the greater the increase in b.p. Which will produce more particles? One mole CaCl₂ or 1 mole NaCl?

CaCl₂ ==> Ca²⁺ + 2Cl^-

NaCl ==> Na⁺ + Cl^-
