D. If both Assertion and Reason are false statements , then mark

Answer

To solve the question regarding the statements about precipitate formation and the relationship between ionic product (K_ip) and solubility product (K_sp), we will analyze each statement step by step.

### Step 1: Understanding the Assertion
The assertion states that precipitate formation occurs when \( K_{ip} > K_{sp} \).

- **Explanation**:
- The ionic product \( K_{ip} \) is the product of the concentrations of the ions in a solution at any given moment.
- The solubility product \( K_{sp} \) is a constant that represents the maximum concentration of ions in a saturated solution at equilibrium.
- When \( K_{ip} \) exceeds \( K_{sp} \), it indicates that the concentration of the ions in solution is greater than what can be maintained in a saturated solution. Thus, the excess ions will precipitate out of the solution.

### Step 2: Understanding the Reason
The reason states that \( K_{ip} = K_{sp} \) for a saturated solution.

- **Explanation**:
- A saturated solution is one where the maximum amount of solute has been dissolved, and no more can be added without forming a precipitate.
- At this point, the ionic product \( K_{ip} \) equals the solubility product \( K_{sp} \), indicating that the solution is at equilibrium.

### Step 3: Evaluating the Truth of Each Statement
- **Assertion**: True. Precipitation occurs when \( K_{ip} > K_{sp} \).
- **Reason**: True. In a saturated solution, \( K_{ip} \) equals \( K_{sp} \).

### Step 4: Analyzing the Relationship Between Assertion and Reason
While both statements are true, the reason does not correctly explain the assertion. The assertion pertains to the condition for precipitation, while the reason describes the condition for saturation.

### Conclusion
Both the assertion and reason are true, but the reason is not the correct explanation for the assertion. Therefore, the correct conclusion is that both statements are true, but the reason is not a correct explanation for the assertion.

### Final Answer
Both A and R are true, but R is not the correct explanation for A.
