Question: In an ideal solution, the enthalpy of mixing is:

Options:

Correct Answer: Zero

Solution:

In an ideal solution, the enthalpy of mixing is zero, indicating no heat is absorbed or released during mixing.

In an ideal solution, the enthalpy of mixing is:

In an ideal solution, the enthalpy of mixing is:

Step 1: Understand what an ideal solution is. An ideal solution is a mixture of two or more substances that behaves in a predictable way according to certain rules.
Step 2: Learn about enthalpy of mixing. This is the heat change that occurs when two substances are mixed together.
Step 3: In an ideal solution, the enthalpy of mixing is zero. This means that when you mix the substances, there is no heat absorbed or released.
Step 4: Realize that this zero enthalpy of mixing indicates that the interactions between the molecules of the different substances are similar to the interactions between the molecules of the same substance.

Ideal Solution – An ideal solution is one where the interactions between different molecules are similar to those between like molecules, resulting in no change in enthalpy upon mixing.
Enthalpy of Mixing – The enthalpy of mixing refers to the heat change that occurs when two substances are mixed; in ideal solutions, this value is zero.
