What is the defining characteristic of a non-ideal solution, and how are positive and negative deviations from Raoult's law determined?
ChemistrySolutionsNEET
Options:
  • A Non-ideal solutions have high heat absorption, and deviations are determined based on solubility.
  • B Non-ideal solutions exhibit deviations from Raoult's law, with positive deviations having higher vapor pressure and negative deviations having lower vapor pressure.
  • C Non-ideal solutions are characterized by zero enthalpy of mixing, and deviations depend on temperature.
  • D Non-ideal solutions are always ideal for a specific range of concentrations.

The correct answer is: Non-ideal solutions exhibit deviations from Raoult's law, with positive deviations having higher vapor pressure and negative deviations having lower vapor pressure.
Non-ideal solutions exhibit deviations from Raoult's law, and positive deviations are characterized by higher vapor pressure than predicted, while negative deviations have lower vapor pressure.
