Narration : 10. Separation by Decantation
- The supernatant can be removed by decantation when the precipitate is heavy and coarse.
- Put a stirring stick on the mouse of the container to avoid trickling of the liquid to the outside of the container.
- Tilt the container and slowly decant the supernatant.
- Next, add suitable washing solvent into the precipitate and stir it. Wait the precipitate to settle, and then decant the washing solvent.
- Repeat this 2 or 3 times to wash the precipitate.
