Question
If you analyze the solubility curve and determine how much sugar (in grams) can be added to 100 grams of water at 30°C to form a saturated solution.

Transcribed Image Text:The image is a graph illustrating the solubility of various substances in water (measured in grams of solute per 100 grams of H₂O) across a range of temperatures (in °C). The graph features solubility curves for seven different substances:
1. **Sugar (C₁₂H₂₂O₁₁):** Solubility increases sharply with temperature, reaching about 300 g/100 g H₂O at 100°C.
2. **KNO₃ (Potassium Nitrate):** Solubility also increases significantly with temperature, from about 20 g/100 g H₂O at 0°C to approximately 240 g/100 g H₂O at 100°C.
3. **NaNO₃ (Sodium Nitrate):** Shows a moderate increase in solubility with temperature, starting around 80 g/100 g H₂O at 0°C and reaching over 150 g/100 g H₂O at 100°C.
4. **NaBr (Sodium Bromide):** Solubility increases with temperature, with values starting at about 90 g/100 g H₂O at 0°C, reaching around 120 g/100 g H₂O at 100°C.
5. **KBr (Potassium Bromide):** Displays increasing solubility with temperature, from about 55 g/100 g H₂O at 0°C to approximately 110 g/100 g H₂O at 100°C.
6. **KCl (Potassium Chloride):** There is a slight increase in solubility with temperature, starting at around 28 g/100 g H₂O at 0°C and rising to about 55 g/100 g H₂O at 100°C.
7. **Ce₂(SO₄)₃ (Cerium(III) Sulfate):** Unlike the others, this substance shows a decrease in solubility with increasing temperature, starting at about 25 g/100 g H₂O at 0°C and decreasing to below 10 g/100 g H₂O at 100°C.
In summary, the graph demonstrates how solubility for most substances increases with temperature, except for cerium(III) sulfate, which decreases.
