B. `Delta H_("mix")=0`
C. `DeltaV_("mix")=0`
D. All ov these

Answer

To determine which property is shown by an ideal solution, we can analyze the characteristics of ideal solutions based on Raoult's law and other related properties. Here is a step-by-step solution:

### Step 1: Understanding Raoult's Law
An ideal solution is defined by its adherence to Raoult's law, which states that the partial vapor pressure of each component in the solution is equal to the vapor pressure of the pure component multiplied by its mole fraction in the solution.

**Hint:** Remember that Raoult's law applies to ideal solutions and helps in understanding the behavior of components in a mixture.

### Step 2: Enthalpy of Mixing
For an ideal solution, the enthalpy of mixing (ΔH_mix) is zero. This means that when two pure components are mixed to form an ideal solution, no heat is absorbed or released during the process.

**Hint:** Consider how heat exchange occurs during mixing and what it implies for ideal solutions.

### Step 3: Volume of Mixing
In an ideal solution, the change in volume upon mixing (ΔV_mix) is also zero. This indicates that the total volume of the solution is equal to the sum of the volumes of the solute and solvent before mixing.

**Hint:** Think about how the volumes of the components relate to the final volume of the solution.

### Step 4: Concentration Changes
In an ideal solution, there is no contraction or expansion of volume when the components are mixed. This means that the volume remains consistent, and there are no significant concentration changes that would affect the overall volume.

**Hint:** Reflect on what happens to the physical properties of the solution when two components are mixed ideally.

### Conclusion
Based on the above analysis, we can conclude that an ideal solution exhibits the following properties:
1. Follows Raoult's law.
2. Enthalpy of mixing (ΔH_mix) is zero.
3. Volume of mixing (ΔV_mix) is zero.

Thus, the correct answer to the question is that all of these properties are shown by an ideal solution.

**Final Answer:** All of these properties are correct (Option D).
