10) Describe the various methods used to desalinate seawater.
Answer: 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.
