***B*** ∻Key Concept∻ ⚹Colligative Properties and Ionic Dissociation⚹ ∻Explanation∻ ⚹The boiling point elevation of a solution depends on the number of particles in solution. Since $AlCl_3$ dissociates into four particles ($Al^{3+}$ and three $Cl^-$), it will have the highest boiling point due to the greatest number of particles resulting from dissociation compared to the other options.⚹◊Which factor determines the boiling point of a solution in Chemistry?⍭ Generate me a similar question◊
