Assertion : Copper metal is turned green when exposed to atmospheric `CO_(2)` and moisture.
Reason: Copper gets covered with a green layer of basic copper carbonate.

Options

A. Statement-1 is true , Statement-2 is true and Statement-2 is correct explanation for Statement-1
B. Statement-1 is true, Statement-2 is True and Statement-2 is Not correct explanation for statement-1
C. Statement-1 is true, Statement-2 is False
D. Statement-1 is False, Statement-2 is True

Answer

To solve the assertion and reason question regarding copper, we can break it down into the following steps:

### Step 1: Understand the Assertion
The assertion states that "Copper metal is turned green when exposed to atmospheric CO2 and moisture." This is true because copper does indeed change color when it interacts with these elements over time.

**Hint:** Think about how metals react with environmental factors like air and moisture.

### Step 2: Analyze the Reason
The reason given is "Copper gets covered with a green layer of basic copper carbonate." This is also true. When copper reacts with carbon dioxide and moisture, it forms basic copper carbonate, which has a green color.

**Hint:** Consider the chemical reactions that occur when copper is exposed to air and moisture.

### Step 3: Chemical Reactions Involved
When copper is exposed to moisture and carbon dioxide, it undergoes a series of reactions:
1. Copper reacts with oxygen in the air to form copper oxide (CuO).
2. The copper oxide then reacts with carbon dioxide (CO2) and water (H2O) to form basic copper carbonate (CuCO3·Cu(OH)2), which is green in color.

**Hint:** Recall the basic principles of corrosion and how metals can react with oxygen and carbon dioxide.

### Step 4: Conclusion
Both the assertion and the reason are true, and the reason correctly explains the assertion. Therefore, the correct answer is that both statements are true, and the reason is the correct explanation for the assertion.

**Hint:** Look for relationships between statements in assertion-reason questions to determine if they support each other.

### Final Answer
Both the assertion and the reason are true, and the reason is the correct explanation for the assertion.
