Determine which compound would raise the boiling point of water the most options: a. 2.0 m alcl3 b. 2.0 m nacl c. 2.0 m cacl2 d. 2.0 m kbr

All of the provided salts will increase the boiling point of water due to Boiling point elevation is considered as one of the colligative properties that only affected by the number of particles present in solution regardless their nature.

All of the choices are considered as electrolytes (ionizes in water) so the one which gives higher number of ions will raise the boiling point the most so the correct answer is A) AlCl₃ due to it ionizes to give 4 ions one Al and 3 Cl while NaCl gives only 2 ions, CaCl₂ gives 3 ions and KBr gives 2 ions 

So the correct answer is A) 2.0 M AlCl₃
