Pemunt is chemically.

Options

A. Hydrated sodium aluminium silcate
B. Sodium hexaphosphate
C. Sodium bicarbonate
D. Calcium hydroxide

Answer

To solve the question about the chemical nature of permutate, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Chemical Nature of Permutate**:
- Permutate is commonly known for its role in water treatment, particularly in the removal of hardness from water.

2. **Determine the Chemical Formula**:
- The chemical formula for permutate is given as Na2Al2Si2O8·xH2O, where "x" represents the number of water molecules associated with the compound.

3. **Evaluate the Options Provided**:
- We need to analyze the options given in the question to determine which one corresponds to permutate.
- The options are:
- A: Hydrated Sodium Aluminum Silicate
- B: Sodium Hexaphosphate (Na6P6O18)
- C: Sodium Bicarbonate (NaHCO3)
- D: Calcium Hydroxide (Ca(OH)2)

4. **Match the Options with Permutate**:
- **Option A**: Hydrated Sodium Aluminum Silicate - This matches the chemical nature of permutate since it contains sodium, aluminum, and silicate, along with water of hydration.
- **Option B**: Sodium Hexaphosphate - This does not match as it contains phosphorus instead of silicon.
- **Option C**: Sodium Bicarbonate - This does not match as it is a different compound entirely.
- **Option D**: Calcium Hydroxide - This does not match as it does not contain aluminum or silicate.

5. **Conclusion**:
- Based on the analysis, the correct answer is **Option A: Hydrated Sodium Aluminum Silicate**.
