Assertion (A): When a piece of copper metal is added to dilute sulphuric acid, the solution turns blue.
Reason (R): Copper reacts with dilute sulphuric acid to form blue copper (II) sulphate solution.

Options

A. Both A and R are true and R is the correct explanation of A.
B. Both A and R are true but R is NOT the correct explanation of A
C. A is true but R is false
D. A is false and R is true.

Explanation

To analyze the assertion and reason provided in the question, we will break down the statements and evaluate their validity step by step.

### Step 1: Understanding the Assertion
The assertion states that when a piece of copper metal is added to dilute sulfuric acid, the solution turns blue.

**Evaluation**:
- Copper (Cu) is a less reactive metal compared to hydrogen. According to the reactivity series, metals that are less reactive than hydrogen do not displace hydrogen from acids.
- Therefore, when copper is added to dilute sulfuric acid (H2SO4), no reaction occurs, and the solution does not turn blue.

**Conclusion**: The assertion is **false**.

### Step 2: Understanding the Reason
The reason states that copper reacts with dilute sulfuric acid to form a blue copper (II) sulfate solution.

**Evaluation**:
- As established, copper does not react with dilute sulfuric acid under normal conditions. The formation of copper (II) sulfate (CuSO4), which is blue, occurs only when copper reacts with concentrated sulfuric acid or when heated.
- Since no reaction occurs with dilute sulfuric acid, the statement that copper reacts to form a blue solution is incorrect.

**Conclusion**: The reason is also **false**.

### Step 3: Final Evaluation
- Assertion (A): False
- Reason (R): False

### Final Answer
Both the assertion and the reason are false. Therefore, the correct choice is that Assertion (A) is false and Reason (R) is false.
