Which Of The Following Condition Is Not Satisfied By An Ideal Solution? (2023)

FAQs

Which of the following condition is not a satisfied by an ideal solution? ›

Hence, the correct option is C i.e. ∆ mix S = 0 .

Ethyl alcohol + Water is a non-Ideal solution.

For an ideal solution that obeys Raoult's Law the following are valid: Heat is neither released nor absorbed during the reaction, ΔmixH=0. The volume of the solution remains the same ΔmixV=0. For an ideal solution, ΔH andΔV for mixing should be zero.

Liquids which have similar structure and polarities form an ideal solution. Since both benzene and toluene are non-polar, the intermolecular forces operating on them are almost similar. So, benzene and toluene form an ideal solution.

Examples of Ideal Solution

Some examples include; Toluene and Benzene. Ethyl Iodide and Ethyl Bromide. Bromobenzene and Chlorobenzene.

Non-ideal solutions can occur two ways: When intermolecular forces between solute and solvent molecules are less strong than between molecules of similar (of the same type) molecules. When intermolecular forces between dissimilar molecules are greater than those between similar molecules.

However, for an ideal solution, entropy mixing (ΔmixS) is not zero. it positive because a solvent (or solute) in a solution has more molecular disorder.

An ideal solution is one in which the connections between molecules are the same for all molecules or ions. Non-ideal Solution: A non-ideal solution is one in which the actions with different molecule constituents in the solution differ.

Non-ideal solutions are of two types: Non-ideal solutions showing positive deviation from Raoult's Law. Non-ideal solutions showing negative deviation from Raoult's Law.

The current belief that water solutions are not “ideal” is due to the assumption that the mass action law is not obeyed and activity coefficients are used to avoid violating an immutable law.
