Sodalime is

Options

A. NaOH
B. `NaOH and CaO`
C. KOH
D. `KOH and CaO`

Explanation

**Step-by-Step Solution:**

1. **Understanding the Name**: The term "Soda Lime" suggests that it consists of two components: "Soda" and "Lime". This indicates that sodium (from "Soda") and calcium oxide (from "Lime") are involved.

2. **Identifying Components**:
- "Soda" refers to sodium compounds, particularly sodium hydroxide (NaOH).
- "Lime" refers to calcium oxide (CaO), which is also known as quick lime or burnt lime.

3. **Formation of Soda Lime**: Soda lime is typically a mixture of sodium hydroxide (NaOH) and calcium oxide (CaO). It can also be formed by heating calcium hydroxide (Ca(OH)₂), which produces calcium oxide (CaO).

4. **Conclusion**: Based on the components identified, soda lime is a mixture of sodium hydroxide (NaOH) and calcium oxide (CaO). Therefore, the correct answer to the question is option 2: NaOH and CaO.

**Final Answer**: Soda Lime is a mixture of NaOH and CaO.
