Lower Sec Science · Secondary 1 · Medium · Solubility
In an experiment, 40 g of solid Z dissolves in 100 ml of water at 30 °C to form a saturated solution. At 50 °C, 60 g of Z can dissolve in 100 ml of water. What does this show about the solubility of Z?
- The solubility of Z increases as temperature increases.
- The solubility of Z decreases as temperature increases.
- The solubility of Z is unchanged by temperature.
- Z is insoluble in water at all temperatures.
