Solubility
Lower Sec Science · Secondary 1 · Medium · Solubility
At 40 °C, 30 g of substance X can dissolve in 100 ml of water to form a saturated solution. A student adds 45 g of X to 100 ml of water at 40 °C and stirs. What will be observed?
- 30 g dissolves and 15 g remains undissolved at the bottom.
- All 45 g dissolves because stirring increases solubility.
- Only 15 g dissolves and 30 g remains undissolved.
- None of the solid dissolves because the solution is already saturated.
