Which of the following substances will not give carbon dioxide on treatment with dilute acid?

Options

A. Marble
B. Limestone
C. Baking soda
D. Lime

Explanation

To determine which substance will not give carbon dioxide when treated with dilute acid, we need to analyze the behavior of different substances when they react with acids.

### Step-by-Step Solution:

1. **Identify the Substances**: The question implies that we have a list of substances to consider. Common examples include marble (calcium carbonate), limestone (calcium carbonate), baking soda (sodium bicarbonate), and lime (calcium oxide).

2. **Understand Reactions with Dilute Acid**:
- **Carbonates and Bicarbonates**: These substances typically release carbon dioxide (CO2) when they react with dilute acids.
- Example: Calcium Carbonate (CaCO3) + HCl → CaCl2 + H2O + CO2 ↑
- Example: Sodium Bicarbonate (NaHCO3) + HCl → NaCl + H2O + CO2 ↑
- **Calcium Oxide (Lime)**: This is not a carbonate or bicarbonate. When it reacts with dilute acid, it does not produce carbon dioxide.
- Example: Calcium Oxide (CaO) + HCl → CaCl2 + H2O (No CO2 is produced)

3. **Conclusion**: Since carbonates and bicarbonates liberate carbon dioxide upon reaction with dilute acids, but calcium oxide (lime) does not, we conclude that lime is the substance that will not give carbon dioxide when treated with dilute acid.

4. **Final Answer**: The substance that will not give carbon dioxide on treatment with dilute acid is **Lime (Calcium Oxide)**.
