Which solution has the greatest osmolarity? A)0.6 M NaCl B)0.35 M AlCl₃ C)0.14 M KF D)0.2 M CaBr₂ E)0.10 M KNO₃

Question

Quizplus · Accepted Answer

Osmolarity is calculated by multiplying the molarity of the solution by the number of particles the solute dissociates into. AlCl3 dissociates into 4 particles (1 Al3+ and 3 Cl-), giving it an osmolarity of 0.35 M x 4 = 1.4 osmol/L, which is the highest among the given options.
