What is the defining characteristic of a non-ideal solution, and how are positive and negative deviations from Raoult's law determined?

Options

  1. ANon-ideal solutions have high heat absorption, and deviations are determined based on solubility.
  2. BNon-ideal solutions exhibit deviations from Raoult's law, with positive deviations having higher vapor pressur
  3. CNon-ideal solutions are characterized by zero enthalpy of mixing, and deviations depend on temperature.
  4. DNon-ideal solutions are always ideal for a specific range of concentrations.

Correct answer

B. Non-ideal solutions exhibit deviations from Raoult's law, with positive deviations having higher vapor pressur

Step-by-step solution

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.
