Question

What is the chemical composition of salt water?

Answer 1

The composition of salt water, or sea water, is about 35 parts of salts per 1,000 parts of fresh water, though the salinity can vary from between 30 to 37 parts per 1,000. The salts are mostly sodium and chloride, the same ions that go into table salt. Other salts present in sea water include magnesium, potassium and calcium.
