Assertion: Alums are crystalline double salts, which are soluble in water.
Reason: The eq.solutions of alums have acidic character due to hydrolysis

Options

A. If both assertion and reason are true and the reason is the correct explanation of assertion
B. If both assertion and reason are true and the reason is not the correct explanation of assertion
C. If assertion is false but reason is true
D. If assertion is true but the reason is false

Explanation

To solve the question, we need to analyze both the assertion and the reason provided.

### Step 1: Analyze the Assertion
The assertion states that "Alums are crystalline double salts, which are soluble in water."

- **Explanation**: Alums are indeed a type of double salt that can be represented by the general formula M2SO4·M'2(SO4)3·24H2O, where M and M' are different metal ions. They are known for their crystalline structure and are soluble in water due to the presence of water molecules in their formula.

### Step 2: Analyze the Reason
The reason states that "The aqueous solutions of alums have acidic character due to hydrolysis."

- **Explanation**: When alums dissolve in water, they undergo hydrolysis, which leads to the formation of acidic solutions. This occurs because the metal ions (especially those from the aluminum group) can react with water to produce H+ ions, resulting in a solution with a pH less than 7, indicating its acidic nature.

### Step 3: Conclusion
Both the assertion and the reason are true statements. However, the reason does not directly explain the assertion. The assertion is about the properties of alums being crystalline and soluble, while the reason discusses the acidic nature of their solutions due to hydrolysis.

### Final Answer
Both the assertion and reason are true, but the reason is not the correct explanation for the assertion. Therefore, the correct option is that both statements are true, but the reason is not the correct explanation for the assertion.
