Fresh water has little or nothing in it except water. Salt water, specifically ocean water, has 3.5 % by weight of various salt, the most dominant being basic NaCl.
Fresh waster, by definition has less than 1% of dissolved salts, but in practice most fresh water has much much less than 1%. For all practical purposes, almost all lakes and streams are nearly as pure as drinking water.
Read on if you want the chemical breakdown of salt water.
More:
Oceans represent 96.5 % of all water and fresh water is 2.5% with 1% saline ground water.
Glaciers, snow, fresh ground water, lakes and streams are fresh water. (Some interesting and peculiar things happen when an inland lake is isolated with no outlet to the ocean, but that is a special case.)
The concentration of salt in all ocean water (also called sea water) is pretty much uniform at 3.5 % by weight. Not all of that is sodium chloride, (Na+, Cl-).
The ocean contains calcium, magnesium, sodium and potassium with bicarbonate sulfate, chlorine and bromine. (If you remove the water, then what is left is, by weight, Cl− 55%, Na+ 30.6%, SO4--, 4 7.7%, Mg2+ 3.7%, Ca++ 1.2%, K+ 1.1%, other 0.7%.)
The small variation in saltiness of the oceans is actually very important and is connected with global ocean currents. Most notably, the antarctic ice forms in the arctic winter squeezing out much of the salt as it freezes and setting up a dense cold ocean current that moves across vast stretches of the worlds oceans.
No, ocean water is salt water. Fresh water would be found in ponds, lakes, or rivers.

Will an egg float in salt water or tap water?
Eggs float in salt water but not in tap water, which is a fresh water. This is because salt water is more dense than fresh water.
Why do freshwater boils faster than saltwater?
fresh water doesnt have salt so it doesnt take as long to have the salt evaporate
What boils faster salt water sugar water oil water vinger wateror normal water?
The correct answer is salt water.
How can you find out how much solute it takes to saturated?
you can always filter out all the extra salt from the water and weigh it with normal water with nothing on it and see how much the salt water weigh by the normal water
Why Solubility of salt is less in heavy water than normal?
It is an isotopic effect on solubility; the normal water is H2O or the heavy water is D2O.
Which water will freeze faster cold water with salt or normal water with salt?
normal water with salt
Why is rain water free of impurities?
rain water doesnt have the salt of salt water
Why does normal water have lower sodium chloride levels than salt water?
Because sodium chloride is salt! Obviously normal water has lower salt levels than salt water.
Will an egg float in salt water or tap water?
Eggs float in salt water but not in tap water, which is a fresh water. This is because salt water is more dense than fresh water.
Why do freshwater boils faster than saltwater?
fresh water doesnt have salt so it doesnt take as long to have the salt evaporate
Does salt water contain more salt then fresh water?
Yes, it is normal.
Does tap water has salt?
No tap water doesnt have salt as it goes through several filtres before reaching your tap.
Why does tap water rust faster than salt water?
It doesnt. salt water usually rusts metals faster because of the mixture of salt, water and oxygen that rusts the metal, but tap water has less oxygen and no salt.
Is the red sea salt or fresh water?
The red sea is normal salt water sea.
Do sweet or salt water make grass grow faster?
no it doesnt
What boils faster salt water sugar water oil water vinger wateror normal water?
The correct answer is salt water.
Do nails rust quicker in salt water or vinegar?
Salt Water Because They Rust In Normal Water Too!
