Study Notes

Crystallization

  • The primary driving force for crystallization is the reduction of supersaturation.

Process of Crystallization

  • The process described in the text is crystallization, which involves a state change from a liquid to a solid.

Filtration Under Suction

  • The purpose of filtration under suction in the purification of solids is to separate the solid particles from the liquid.
  • The role of a filter in the process of filtration under suction is to act as a barrier, allowing the liquid to pass through while retaining the solid particles.
  • Filtration under suction contributes to the purification of solids by removing impurities from the solid particles.
  • The primary purpose of filtration under suction is to quickly and efficiently separate the solid particles from the liquid, resulting in a more pure solid.
  • Suction plays a crucial role in the process of filtration under suction, as it helps to pull the liquid through the filter, allowing for faster and more efficient separation.
  • The main benefit of using filtration under suction over regular filtration is that it is faster and more efficient, resulting in a more pure solid.
