Answer to Question 1

Electrolysis Method: A current is run through positive and negative electrodes in freshwater separated by semipermeable membranes from seawater. Distillation Method: Saltwater is boiled and the water vapor is passed through a cooling condenser, where it condenses as freshwater. Freeze Separation Method: Seawater is frozen and thawed multiple times, with the salts washed from the ice between each thawing. Reverse Osmosis Method: Water on the salty side of a semipermeable membrane is pushed under high pressure through the membrane to the freshwater side.
