Correct Option
The correct option is (c).
Explanation
Quick lime is a chemical compound known as Calcium Oxide (CaO). As a metallic oxide, it exhibits basic properties and is utilized in various industrial and agricultural applications, particularly involving neutralization reactions.
Statement-wise Analysis
- Statement 1 is Correct: The chemical name of Quick Lime is Calcium Oxide (CaO). It is typically produced by the thermal decomposition of limestone (Calcium Carbonate).
- Statement 2 is Incorrect: Quick lime is basic in nature. Therefore, it is used to treat acidic soil to neutralize the excess acidity. To treat basic soil, organic matter is typically added, which releases acids to neutralize the basicity.
- Statement 3 is Correct: Calcium Oxide is a metallic oxide. Metallic oxides are inherently basic because they react with water to form bases (hydroxides), such as Calcium Hydroxide (Slaked Lime).
Key Takeaway
Quick Lime (CaO) is a basic oxide used to neutralize acidic soil; it is distinct from Slaked Lime (Calcium Hydroxide), though both are basic.
