Solubility
Lower Sec Science · Secondary 1 · Hard · Solubility
A student heats 100 g of water from 20 °C to 80 °C and measures how much solid Y can dissolve. The graph of solubility of Y in 100 g of water is:
- At 20 °C: 30 g
- At 40 °C: 40 g
- At 60 °C: 55 g
- At 80 °C: 70 g
If the student adds 65 g of solid Y to 100 g of water at 60 °C and stirs, how much solid Y will remain undissolved?
- At 20 °C: 30 g
- At 40 °C: 40 g
- At 60 °C: 55 g
- At 80 °C: 70 g
If the student adds 65 g of solid Y to 100 g of water at 60 °C and stirs, how much solid Y will remain undissolved?
- 0 g
- 5 g
- 10 g
- 15 g
