How will the boiling point of a liter of water containing 1 mole of sodium chloride (NaCl) compare with that of a liter of water containing 1 mole of calcium chloride (CaCl2)? Explain your answer.

Question

itsbribro · Answer

I'll just explain it in a small sentence...basically because of the oxidation numbers the water with the NaCl has a lower boiling point.

Hint: how many moles of Cl- ions will be liberated in either case? 
Write up the equations for the dissociations and this should make sense. CaCl2 has double the number of moles of Cl- compared to NaCl

photon336 · Answer

more ions dissolved in a solution will make the boiling point higher. 

count the number of ions produced when the substance is dissolved in water. 

$$NaCl \rightarrow Na^{+} + Cl^{-}$$

$$CaCl_{2} \rightarrow Ca^{2+} + 2Cl^{-}$$
