Unknown Principle In contrast to gases, the higher the temperature of the water, the better salts dissolve in it. By supercooling them, metastabile supersaturated solutions can be prepared which exhibit a higher concentration than that corresponding to the thermodynamic equilibrium quantity at a given temperature. In this experiment students prepare saturated (and supersatured) solutions at different temperatures and investigate the properties of this solutions. Learning objectives - Solubility of solids in water
- saturated and supersaturated solution
Benefits - Easy teaching and efficient learning by using interactive experimentation PHYWE-Software
- Experiment is part of a complete solution set with experiments for all Inorganic Chemistry matched with international curriculum: all topics are covered
