← ScienceWhich consequence results when the van't Hoff factor deviates significantly enough from its anticipated constant value in a concentrated electrolyte solution?
A)Raoult's law displays minor deviations
B)Boiling point elevation diminishes markedly
C)Freezing point depression increases slightly
D)Osmotic pressure changes unpredictably✓
💡 Explanation
Large deviations disrupt ideal solution behavior because ion pairing dominates, diminishing effectively free ions. This modifies colligative properties, with osmotic pressure changing unpredictably rather than other colligative shifts, because it is more sensitive to concentration alterations.
