Read each question carefully and answer to the best of your ability. Refer to the provided solubility curve diagram if necessary.
Use the following hypothetical solubility curve for questions 1-4. (Note: This is a simplified representation for educational purposes).
1. At what temperature is the solubility of Substance A approximately 60 g/100g H₂O?
20°C
40°C
60°C
80°C
2. Which substance shows an increase in solubility as temperature increases?
Substance A
Substance B
Both A and B
Neither A nor B
3. A solution containing 50 g of Substance A in 100g of water at 20°C would be considered .
4. If a saturated solution of Substance B at 80°C is cooled to 20°C, approximately g of Substance B would precipitate out.
5. Explain what a solubility curve represents and how it is used.
6. Describe the general trend for the solubility of most solids as temperature increases. Are there exceptions? Explain.
7. For most gases, solubility in water increases as temperature increases.
True
False
8. A point below the solubility curve represents an unsaturated solution.
True
False
