Assuming complete ionization for the electrolytes, which of the following equimolal () aqueous solut — Solutions and Colligative Properties Chemistry Question
Question
Assuming complete $100\%$ ionization for the electrolytes, which of the following equimolal ($0.10\text{ m}$) aqueous solutions will exhibit the absolute highest boiling point?
Answer: C
💡 Solution & Explanation
Elevation in boiling point ($\Delta T_b$) is proportional to the effective particle concentration ($i \times m$). Glucose $i=1$, $KCl$ $i=2$, $K_2SO_4$ $i=3$, $Al_2(SO_4)_3$ $i=5$. Since Aluminum sulphate produces 5 particles, it yields the highest $\Delta T_b$ and thus the highest boiling point.
