What is ocean water made out of?

Answer 1

Seawater is a solution, with the solvent of water (H2O), and common solutes of ionized salt (Na+ and Cl-), Magnesium, Sulfur, Potassium, Calcium, Bromine, and Carbon. There are a variety of other elements, but they are in much smaller concentrations.

Answer 2

Homogeneous unless you include sea creatures and floating debris or debris that is in the water. Because you cannot separate ocean water from the chemicals or solvents that are in the water without evaporating the water or using a funnel which probably won't work (the funnel that is) anyway.

Answer 3

A complex mixture of gases and salts including NaCl.

Answer 4

Salt
