Solubility
Lower Sec Science · Secondary 1 · Hard · Solubility
A student dissolves 20 g of salt in 100 ml of water at 25 °C to form a saturated solution. He then heats the solution to 60 °C. What will most likely happen to the salt in the solution?
- All 20 g of salt remains dissolved because solubility increases with temperature.
- Some salt will crystallise out because solubility decreases with temperature.
- All the salt will come out of solution and form a solid layer.
- The salt will evaporate together with the water.
