The question more or less answers itself. You put an electric current through it and hydrogen forms at the cathode and oxygen forms at the anode.
Slightly alkaline (from 7.1 to 8.5)
You can use evaporation, which is where you boil the water until all of it evaporates. Another way is to freeze water, leaving the salt on top.
Ordinary simple filtration cannot separate the salt from the salty water, unfortunately.But the guys who row across the Atlantic use a method called reverse osmosis to recover the fresh water from the sea water.Have a look at reverse osmosis in the related link below._______________________________________________________________Filtration is the process whereby you separate smaller molecules from a mixture of both smaller and larger molecules.Maybe you should try distillation, the process whereby you can separate salt from saltwater through boiling (evaporation) and condensation by using some basic apparatus that could be found in labs.
Fahrenheit
because the sea water is salt water
Separate the sand grains using a fine mesh. Separate salt from the water by using evaporation (leaving the salt crystals behind), and condensation (turning the evaporated water vapor back into a liquid).
no
By the sea where there is plenty of salt water. (Brine)
Crystalisation
no
ask a friend
yes
Urinate in the sea to create a barrier between the oil and sea water, thus separating the two.
They are separate bodies of water in and beyond the Mediterranean Sea
Mediterranean Sea
The Red Sea.
evaporate the water or evaporation. condense the water vapour or condensation
