During the purification process, filtration separates the

• disolved salts

• suspended particles

• all ions (cations and anions)

• organic substances

Which of these particles is NOT able to pass through a paper filter?

• bacteria

• water

• viruses

• large piece of dirt

Th components of filtration are separated based on

• boiling point

• solubility

• particle size

• ion charge

What is the process of separating components based on their boiling point?

• Decantation

• Crystallization

• Distillation

• Filtration

Which of the following is the best method of separating components based on their particle size?

• Ion exchange

• Ultrafiltration

• Simple dilstillation

• Reverse Osmosis

In Natural Osmosis

• The water flows from less concentrated to more concentrated solution

• The water flows from more concnetrated to less concentrated solution

• The ions flow from less concentrated to more concentrated solution

• The water flow from more concnetrated to less concentrated solution
