    • • What is filtration?Filtration is the process of separating tiny insoluble particles such as soil fromliquids. Filter paper is placed in the funnel, then the water is poured into thefilter paper, the soil will stay onto the paper as the soil is too big, and the waterwill go through. Filter papers’ holes are so tiny that they cannot be seen with thenaked eye.What do we use it for?FiltrationFiltration
    • • What is decanting?• When a heavy insoluble substance such as sand sinks to the bottom of a solvent. Then by pouring the solvent into another storage area, the water will pour and the sand won’t be able to catch up as it is too heavy.Decanting
    • • What is floatation? • When an insoluble solute such as oil floats to the top of a solvent such as water. To separate this suspension, the suspension is poured into a separating funnel, which let the water flows down when the tap is open, and as all the water is gone, the tap is closed and the oil stays in the funnel.Floatation
    • • What is evaporation?• Evaporation is the process of turning a liquid into a gas. Water vapour can then be turned back into a liquid by using a condenser.Evaporation
    • • What is Distillation?• Distillation is the process of separating water and salt. First the salt water is placed in the boiling flask. A Bunsen burner is put under the flask. As the boiling flask heats up the water and turns it into steam, the steam travels upwards into the condenser and the steam condenses into pure water, and goes into the conical flask.Distillation
