Filtration and Crystallisation

• Filtering can separate a solid which does not dissolve from a liquid
• Crystallisation- The mixture is heated until all the liquid has evaporated, the dissolved solid is left behind over a length of time
• Formulations are mixtures that have been prepared using a specific formula. Like…

  • Precise amount of different components
  • Have a particular function. medicines , paint
• Filtration is a separation technique which separates an insoluble solid from a liquid
• • Soluble means a substance that can dissolve on a specific liquid.

• • Solute is the substance that is being dissolved.
  • Solvent is the liquid that dissolves the solute.
  • Solution is the formed mixture when the solute is dissolved in the solvent.
