Which statements are false?

Options

A. Manufacture of NaOH is done by Solvay process
B. Manufacture of `K_(2)CO_(3)` is done by Solvay process
C. Manufacture of NaOH is done by Castner Keliner process
D. Manufacture of `NaHCO_(3)` is done by Solvay process

Answer

To determine which statements are false, let's analyze each option based on the information provided in the video transcript regarding the Solvay and Kastner-Kelliner processes.

### Step-by-Step Solution:

1. **Option 1: Manufacture of sodium hydroxide is done by Solvay's process.**
- The Solvay process is primarily used for the manufacture of sodium carbonate (soda ash), not sodium hydroxide. Therefore, this statement is **false**.

2. **Option 2: Manufacture of potassium carbonate is done by Solvay's process.**
- The Solvay process does not produce potassium carbonate; it is specifically designed for sodium carbonate. Thus, this statement is also **false**.

3. **Option 3: Manufacture of sodium hydroxide is done by Kastner-Kelliner process.**
- The Kastner-Kelliner process is indeed used for the manufacture of sodium hydroxide through the electrolysis of sodium chloride. This statement is **true**.

4. **Option 4: Manufacture of sodium bicarbonate is done by Solvay's process.**
- The Solvay process can produce sodium bicarbonate as an intermediate product, but it is primarily known for producing sodium carbonate. However, since sodium bicarbonate can be produced in the process, this statement is **true**.

### Summary of Statements:
- **False Statements:**
- Option 1: Manufacture of sodium hydroxide is done by Solvay's process.
- Option 2: Manufacture of potassium carbonate is done by Solvay's process.

- **True Statements:**
- Option 3: Manufacture of sodium hydroxide is done by Kastner-Kelliner process.
- Option 4: Manufacture of sodium bicarbonate is done by Solvay's process.

### Final Answer:
The false statements are **Option 1 and Option 2**.
