What are the two important properties of ideal solutions?
Understand the Problem
The question is asking for the key properties of ideal solutions, specifically which of the provided options correctly identify these properties related to enthalpy and volume of mixing.
Answer
Enthalpy of mixing is zero, and volume of mixing is zero.
The enthalpy of mixing of the pure components to form the solution is zero, and the volume of mixing is also zero.
Answer for screen readers
The enthalpy of mixing of the pure components to form the solution is zero, and the volume of mixing is also zero.
More Information
Ideal solutions are theoretical concepts that represent mixtures where the enthalpy of mixing is zero because there are no energy changes when two substances are mixed. This indicates perfect intermolecular interactions between molecules of different substances, similar to those in each pure component.
Tips
A common mistake is confusing ideal solution properties with those of real solutions where interactions lead to enthalpy and volume changes.
