Answer 1

Here are the IUPAC names, chemical formulas, and common uses for limewater, quicklime, gypsum, caustic soda, and caustic potash:

### 1. Limewater
- **IUPAC Name:** Calcium hydroxide solution
- **Chemical Formula:** Ca(OH)₂ (dissolved in water)
- **Uses:**
- Used to test for carbon dioxide, as it turns cloudy when CO₂ is bubbled through it.
- In horticulture for adjusting soil pH.
- As a building material (component of mortar).
- In water treatment to soften water and remove impurities.

### 2. Quicklime
- **IUPAC Name:** Calcium oxide
- **Chemical Formula:** CaO
- **Uses:**
- Used in the production of cement and mortar.
- In steel manufacturing as a flux.
- For water treatment and in the paper industry.
- In chemical processes, including the production of calcium hydroxide.

### 3. Gypsum
- **IUPAC Name:** Calcium sulfate dihydrate
- **Chemical Formula:** CaSO₄·2H₂O
- **Uses:**
- Used in the construction industry for making drywall (plasterboard).
- As a soil conditioner in agriculture to improve soil structure.
- In the manufacture of cement.
- As a mold for casting in various industrial applications.

### 4. Caustic Soda

- **Chemical Formula:** NaOH
- **Uses:**
- Used in soap and detergent manufacturing.
- In chemical industries as a strong base in various chemical reactions.
- For pH adjustment and water treatment.
- As a drain cleaner and in food processing.

### 5. Caustic Potash
- **IUPAC Name:** Potassium hydroxide
- **Chemical Formula:** KOH
- **Uses:**
- Used in the production of biodiesel.
- In the manufacturing of fertilizers.
- As a strong base in various chemical processes.
- In soap making, similar to caustic soda but for potassium-based soaps.

These compounds are important in various industrial, agricultural, and domestic applications.
