Soda lime is a mixture of

Options

A. `Na+CaO+H_(2)O`
B. `CaO+NaOH(aq)`
C. `NaOH+CaCO_(3)`
D. `NaHCO_(3)+CaO`

Answer

To solve the question "Soda lime is a mixture of," we can follow these steps:

### Step 1: Understand the Components of Soda Lime
Soda lime is a chemical mixture commonly used in various applications, particularly in the absorption of carbon dioxide. It primarily consists of two main components.

**Hint:** Think about the common uses of soda lime and what compounds might be involved in those processes.

### Step 2: Identify the Main Components
From the information provided, soda lime is primarily made up of:
- **Calcium Hydroxide (Ca(OH)₂)**: This is the main component, making up about 94% of soda lime.
- **Sodium Hydroxide (NaOH)**: This is the second component, making up about 5%.
- **Potassium Hydroxide (KOH)**: This is present in very small amounts, less than 0.1%.

**Hint:** Consider the chemical formulas of the components mentioned and their common names.

### Step 3: Write the Chemical Formulas
Now, we can write the chemical formulas for the main components:
- Calcium Hydroxide: **Ca(OH)₂**
- Sodium Hydroxide: **NaOH**
- Potassium Hydroxide: **KOH**

**Hint:** Remember that the question asks for the main components, so focus on the most significant ones.

### Step 4: Conclude the Mixture Composition
Based on the information gathered, we can conclude that soda lime is a mixture of:
- Calcium Hydroxide (Ca(OH)₂)
- Sodium Hydroxide (NaOH)

**Hint:** Look for the option that includes these two compounds in the answer choices.

### Step 5: Select the Correct Option
After analyzing the components, we find that the correct option for the mixture of soda lime is:
- **Ca(OH)₂ and NaOH**

**Hint:** Ensure that the option you choose reflects the major components identified.

### Final Answer
Soda lime is a mixture of Calcium Hydroxide (Ca(OH)₂) and Sodium Hydroxide (NaOH).
