### Solubility of Various Substances in Water

This graph demonstrates the solubility of different solutes in water, measured as grams of solute per 100 grams of water, across a range of temperatures from 0°C to 100°C.

#### Key Observations:

1. **KI (Potassium Iodide):**
   - Solubility increases significantly with temperature, starting at about 130 g at 0°C and rising to over 150 g at 100°C.

2. **NaNO₃ (Sodium Nitrate):**
   - Solubility rises steeply from around 75 g at 0°C to about 130 g at 100°C.

3. **KNO₃ (Potassium Nitrate):**
   - Shows a marked increase in solubility with temperature, from approximately 20 g at 0°C to around 90 g at 100°C.

4. **NH₃ (Ammonia):**
   - Solubility decreases as temperature increases, starting at about 90 g at 0°C and dropping to around 30 g at 100°C.

5. **NH₄Cl (Ammonium Chloride):**
   - Solubility increases steadily from about 30 g at 0°C to approximately 60 g at 100°C.

6. **KCl (Potassium Chloride):**
   - The solubility curve shows a moderate increase from 30 g at 0°C to about 50 g at 100°C.

7. **NaCl (Sodium Chloride):**
   - Solubility increases slightly, from roughly 35 g at 0°C to around 40 g at 100°C.

8. **KClO₃ (Potassium Chlorate):**
   - Solubility rises slowly from about 5 g at 0°C to approximately 30 g at 100°C.

9. **Ce₂(SO₄)₃ (Cerium(III) Sulfate):**
   - Exhibits a decrease in solubility with temperature, starting at about 20 g at 0°C and declining slightly.

#### Conclusion:

The graph highlights how the solubility of most solids increases with temperature. However, some substances like NH₃ and Ce₂(SO₄)₃ display decreasing solubility with rising temperatures. This information is crucial for understanding how temperature affects the behavior
