The colligative properties of solutions depend on the total concentration of solute particles, regardless of whether the particles are ions or molecules. TABLE Q1 describes the measured and ideal values of van't Hoff factors, i for several substances at 25 °C. TABLE Q1 Compound Measured i values Ideal i 0.100 m 0.0100 m 0.00100 m values NaCI 1.87 1.94 1.97 2.00 K2SO4 2.32 2.70 2.84 3.00 M9SO4 1.21 1.53 1.82 2.00 Glucose 1.00 1.00 1.00 1.00 i. Using your knowledge in colligative properties, explain the departure from the ideal behaviour and the differences observed for the i values for all compounds at different concentrations in TABLE Q1.
