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
